By default, pip uses ``importlib.metadata`` on Python 3.11+, and ``pkg_resources`` otherwise. Up to Python 3.13, This can be overridden by a couple of ways: * If environment variable ``_PIP_USE_IMPORTLIB_METADATA`` is set, it dictates whether ``importlib.metadata`` is used, for Python <3.14. * On Python 3.11, 3.12 and 3.13, Python distributors can patch ``importlib.metadata`` to add a global constant ``_PIP_USE_IMPORTLIB_METADATA = False``. This makes pip use ``pkg_resources`` (unless the user set the aforementioned environment variable to *True*). On Python 3.14+, the ``pkg_resources`` backend cannot be used. )T_PIP_USE_IMPORTLIB_METADATANr Fr) sys version_info contextlibsuppressKeyError ValueErrorrrosenvironimportlib.metadatagetattrmetadata importlibr(_/var/www/html/flask_server/venv/lib/python3.10/site-packages/pip/_internal/metadata/__init__.py_should_use_importlib_metadatas  r*NonecCs:tjdkrdSddl}t|jdrdStddddddS) Nrrrz7Using the pkg_resources metadata backend is deprecated.zpto use the default importlib.metadata backend, by unsetting the _PIP_USE_IMPORTLIB_METADATA environment variablez26.3i4)reason replacementgone_inissue)rrr#hasattrr%rr&r(r(r))_emit_pkg_resources_deprecation_if_needed?s   r1c@s&eZdZUded<ded<ded<dS)Backendz%Literal['importlib', 'pkg_resources']NAMEztype[BaseDistribution] Distributionztype[BaseEnvironment] EnvironmentN)__name__ __module__ __qualname____annotations__r(r(r(r)r2Xs  r2cCs8trddlm}tt|Stddlm}tt|S)Nr r&) pkg_resources)r*r'rr2r1r:)r'r:r(r(r)r^s     rr cCs tjS)aGet the default representation for the current environment.
