    If a package is not found in the Pyodide repository it will be loaded from

    built by Pyodide.

    When used in web browsers, downloads from PyPI will be cached. When run in
    Node.js, packages are currently not cached, and will be re-downloaded each
    time ``micropip.install`` is run.

    Parameters
    ----------
    requirements :

        A requirement or list of requirements to install. Each requirement is a
        string, which should be either a package name or a wheel URI:

        - If the requirement does not end in ``.whl``, it will be interpreted as
          a package name. A package with this name must either be present
          in the Pyodide lock file or on PyPI.

        - If the requirement ends in ``.whl``, it is a wheel URI. The part of
          the requirement after the last ``/``  must be a valid wheel name in
          compliance with the `PEP 427 naming convention
          <https://www.python.org/dev/peps/pep-0427/#file-format>`_.

        - If a wheel URI starts with ``emfs:``, it will be interpreted as a path
          in the Emscripten file system (Pyodide's file system). E.g.,
          ``emfs:../relative/path/wheel.whl`` or ``emfs:/absolute/path/wheel.whl``.
          In this case, only .whl files are supported.

        - If a wheel URI requirement starts with ``http:`` or ``https:`` it will
          be interpreted as a URL.

        - In node, you can access the native file system using a URI that starts
          with ``file:``. In the browser this will not work.

    keep_going :

        This parameter decides the behavior of the micropip when it encounters a
        Python package without a pure Python wheel while doing dependency
        resolution:

        - If ``False``, an error will be raised on first package with a missing
          wheel.

        - If ``True``, the micropip will keep going after the first error, and
          report a list of errors at the end.

    deps :

        If ``True``, install dependencies specified in METADATA file for each
        package. Otherwise do not install dependencies.

    credentials :

        This parameter specifies the value of ``credentials`` when calling the

        function which is used to download the package.

        If ``True``, include pre-release and development versions. By default,
        micropip only finds stable versions.

    index_urls :

        A list of URLs or a single URL to use as the package index when looking
        up packages. If None, *https://pypi.org/pypi/{package_name}/json* is used.

        - The index URL should support the
          `JSON API <https://warehouse.pypa.io/api-reference/json/>`__ .

        - The index URL may contain the placeholder {package_name} which will be
          replaced with the package name when looking up a package. If it does not
          contain the placeholder, the package name will be appended to the URL.

        - If a list of URLs is provided, micropip will try each URL in order until
          it finds a package. If no package is found, an error will be raised.

    verbose :
        Print more information about the process.
        By default, micropip is silent. Setting ``verbose=True`` will print

    Add a mock version of a package to the package dictionary.

    This means that if it is a dependency, it is skipped on install.

    By default a single empty module is installed with the same
    name as the package. You can alternatively give one or more modules to make a
    set of named modules.

    The modules parameter is usually a dictionary mapping module name to module text.

            print("This is run on import of module")

    If you are adding the module in non-persistent mode, you can also pass functions
    which are used to initialize the module on loading (as in `importlib.abc.loader.exec_module` ).
    This allows you to do things like use `unittest.mock.MagicMock` classes for modules.

    modules :

        The string contains the source of the mock module or is blank for
        an empty module.

    persistent :

        If this is True, modules will be written to the file system, so they
        persist between runs of python (assuming the file system persists).
        If it is False, modules will be stored inside micropip in memory only.

--------------------------------

2.1. Grants

Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:

(a) under intellectual property rights (other than patent or trademark)
    Licensable by such Contributor to use, reproduce, make available,
    modify, display, perform, distribute, and otherwise exploit its
    Contributions, either on an unmodified basis, with Modifications, or
    as part of a Larger Work; and

(b) under Patent Claims of such Contributor to make, use, sell, offer
    for sale, have made, import, and otherwise transfer either its
    Contributions or its Contributor Version.

2.2. Effective Date

The licenses granted in Section 2.1 with respect to any Contribution
become effective for each Contribution on the date the Contributor first
distributes such Contribution.

2.3. Limitations on Grant Scope

The licenses granted in this Section 2 are the only rights granted under
this License. No additional rights or licenses will be implied from the
distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:

(a) for any code that a Contributor has removed from Covered Software;
    or

(b) for infringements caused by: (i) Your and any other third party's
    modifications of Covered Software, or (ii) the combination of its
    Contributions with other software (except as part of its Contributor
    Version); or

(c) under Patent Claims infringed by Covered Software in the absence of
    its Contributions.

This License does not grant any rights in the trademarks, service marks,
or logos of any Contributor (except as may be necessary to comply with
the notice requirements in Section 3.4).

2.4. Subsequent Licenses

No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).

2.5. Representation

Each Contributor represents that the Contributor believes its
Contributions are its original creation(s) or it has sufficient rights
to grant the rights to its Contributions conveyed by this License.

2.6. Fair Use

This License is not intended to limit any rights You have under
applicable copyright doctrines of fair use, fair dealing, or other
equivalents.

2.7. Conditions

Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.

3. Responsibilities
-------------------

3.1. Distribution of Source Form

All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.

3.2. Distribution of Executable Form

If You distribute Covered Software in Executable Form then:

(a) such Covered Software must also be made available in Source Code
    Form, as described in Section 3.1, and You must inform recipients of
    the Executable Form how they can obtain a copy of such Source Code
    Form by reasonable means in a timely manner, at a charge no more
    than the cost of distribution to the recipient; and

(b) You may distribute such Executable Form under the terms of this
    License, or sublicense it under different terms, provided that the
    license for the Executable Form does not attempt to limit or alter
    the recipients' rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).

3.4. Notices

You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.

4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------

If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.

5. Termination
--------------

5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.

cross-claims or counter-claims.

9. Miscellaneous
----------------

This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be

        2.2. Effective Date
        
        The licenses granted in Section 2.1 with respect to any Contribution
        become effective for each Contribution on the date the Contributor first
        distributes such Contribution.
        
        2.3. Limitations on Grant Scope
        
        The licenses granted in this Section 2 are the only rights granted under
        this License. No additional rights or licenses will be implied from the
        distribution or licensing of Covered Software under this License.
        Notwithstanding Section 2.1(b) above, no patent license is granted by a
        Contributor:
        
        (a) for any code that a Contributor has removed from Covered Software;
            or
        
        (b) for infringements caused by: (i) Your and any other third party's
            modifications of Covered Software, or (ii) the combination of its
            Contributions with other software (except as part of its Contributor
            Version); or
        
        (c) under Patent Claims infringed by Covered Software in the absence of
            its Contributions.
        
        This License does not grant any rights in the trademarks, service marks,
        or logos of any Contributor (except as may be necessary to comply with
        the notice requirements in Section 3.4).
        
        2.4. Subsequent Licenses
        
        No Contributor makes additional grants as a result of Your choice to
        distribute the Covered Software under a subsequent version of this
        License (see Section 10.2) or under the terms of a Secondary License (if
        permitted under the terms of Section 3.3).
        
        2.5. Representation
        
        Each Contributor represents that the Contributor believes its
        Contributions are its original creation(s) or it has sufficient rights
        to grant the rights to its Contributions conveyed by this License.
        
        2.6. Fair Use
        
        This License is not intended to limit any rights You have under
        applicable copyright doctrines of fair use, fair dealing, or other
        equivalents.
        
        2.7. Conditions
        
        Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
        in Section 2.1.
        
        3. Responsibilities
        -------------------
        
        3.1. Distribution of Source Form
        
        All distribution of Covered Software in Source Code Form, including any
        Modifications that You create or to which You contribute, must be under
        the terms of this License. You must inform recipients that the Source
        Code Form of the Covered Software is governed by the terms of this
        License, and how they can obtain a copy of this License. You may not
        attempt to alter or restrict the recipients' rights in the Source Code
        Form.
        
        3.2. Distribution of Executable Form
        
        If You distribute Covered Software in Executable Form then:
        
        (a) such Covered Software must also be made available in Source Code
            Form, as described in Section 3.1, and You must inform recipients of
            the Executable Form how they can obtain a copy of such Source Code
            Form by reasonable means in a timely manner, at a charge no more
            than the cost of distribution to the recipient; and
        
        (b) You may distribute such Executable Form under the terms of this
            License, or sublicense it under different terms, provided that the
            license for the Executable Form does not attempt to limit or alter
            the recipients' rights in the Source Code Form under this License.
        
        3.3. Distribution of a Larger Work
        
        You may create and distribute a Larger Work under terms of Your choice,
        provided that You also comply with the requirements of this License for
        the Covered Software. If the Larger Work is a combination of Covered
        Software with a work governed by one or more Secondary Licenses, and the
        Covered Software is not Incompatible With Secondary Licenses, this
        License permits You to additionally distribute such Covered Software
        under the terms of such Secondary License(s), so that the recipient of
        the Larger Work may, at their option, further distribute the Covered
        Software under the terms of either this License or such Secondary
        License(s).
        
        3.4. Notices
        
        You may not remove or alter the substance of any license notices
        (including copyright notices, patent notices, disclaimers of warranty,
        or limitations of liability) contained within the Source Code Form of
        the Covered Software, except that You may alter any license notices to
        the extent required to remedy known factual inaccuracies.
        
        3.5. Application of Additional Terms
        
        You may choose to offer, and to charge a fee for, warranty, support,
        indemnity or liability obligations to one or more recipients of Covered
        Software. However, You may do so only on Your own behalf, and not on
        behalf of any Contributor. You must make it absolutely clear that any
        such warranty, support, indemnity, or liability obligation is offered by
        You alone, and You hereby agree to indemnify every Contributor for any
        liability incurred by such Contributor as a result of warranty, support,
        indemnity or liability terms You offer. You may include additional
        disclaimers of warranty and limitations of liability specific to any
        jurisdiction.
        
        4. Inability to Comply Due to Statute or Regulation
        ---------------------------------------------------
        
        If it is impossible for You to comply with any of the terms of this
        License with respect to some or all of the Covered Software due to
        statute, judicial order, or regulation then You must: (a) comply with
        the terms of this License to the maximum extent possible; and (b)
        describe the limitations and the code they affect. Such description must
        be placed in a text file included with all distributions of the Covered
        Software under this License. Except to the extent prohibited by statute
        or regulation, such description must be sufficiently detailed for a
        recipient of ordinary skill to be able to understand it.
        
        5. Termination
        --------------
        
        5.1. The rights granted under this License will terminate automatically
        if You fail to comply with any of its terms. However, if You become
        compliant, then the rights granted under this License from a particular
        Contributor are reinstated (a) provisionally, unless and until such
        Contributor explicitly and finally terminates Your grants, and (b) on an
        ongoing basis, if such Contributor fails to notify You of the
        non-compliance by some reasonable means prior to 60 days after You have
        come back into compliance. Moreover, Your grants from a particular
        Contributor are reinstated on an ongoing basis if such Contributor
        notifies You of the non-compliance by some reasonable means, this is the
        first time You have received notice of non-compliance with this License
        from such Contributor, and You become compliant prior to 30 days after
        Your receipt of the notice.
        
        5.2. If You initiate litigation against any entity by asserting a patent
        infringement claim (excluding declaratory judgment actions,
        counter-claims, and cross-claims) alleging that a Contributor Version
        directly or indirectly infringes any patent, then the rights granted to
        You by any and all Contributors for the Covered Software under Section
        2.1 of this License shall terminate.
        
        5.3. In the event of termination under Sections 5.1 or 5.2 above, all
        end user license agreements (excluding distributors and resellers) which
        have been validly granted by You or Your distributors under this License
        prior to termination shall survive termination.

        *                                                                      *

        *  special, incidental, or consequential damages of any character      *
        *  including, without limitation, damages for lost profits, loss of    *

        8. Litigation
        -------------
        
        Any litigation relating to this License may be brought only in the
        courts of a jurisdiction where the defendant maintains its principal
        place of business and such litigation shall be governed by laws of that
        jurisdiction, without reference to its conflict-of-law provisions.
        Nothing in this Section shall prevent a party's ability to bring
        cross-claims or counter-claims.
        
        9. Miscellaneous
        ----------------
        
        This License represents the complete agreement concerning the subject
        matter hereof. If any provision of this License is held to be
        unenforceable, such provision shall be reformed only to the extent
        necessary to make it enforceable. Any law or regulation which provides
        that the language of a contract shall be construed against the drafter
        shall not be used to construe this License against a Contributor.
        
        10. Versions of the License
        ---------------------------
        
        10.1. New Versions
        
        Mozilla Foundation is the license steward. Except as provided in Section
        10.3, no one other than the license steward has the right to modify or
        publish new versions of this License. Each version will be given a
        distinguishing version number.
        
        10.2. Effect of New Versions
        
        You may distribute the Covered Software under the terms of the version
        of the License under which You originally received the Covered Software,
        or under the terms of any subsequent version published by the license
        steward.
        
        10.3. Modified Versions
        
        If you create software not governed by this License, and you want to
        create a new license for such software, you may create and use a
        modified version of this License if you rename the license and remove
        any references to the name of the license steward (except to note that
        such modified license differs from this License).
        
        10.4. Distributing Source Code Form that is Incompatible With Secondary
        Licenses
        
        If You choose to distribute Source Code Form that is Incompatible With
        Secondary Licenses under the terms of this version of the License, the
        notice described in Exhibit B of this License must be attached.

        If it is not possible or desirable to put the notice in a particular
        file, then You may include the notice in a location (such as a LICENSE
        file in a relevant directory) where a recipient would be likely to look
        for such a notice.
        
        You may add additional accurate notices of copyright ownership.
        
        Exhibit B - "Incompatible With Secondary Licenses" Notice
        ---------------------------------------------------------
