By default, pip uses ``importlib.metadata`` on Python 3.11+, and ``pkg_resourcess`` otherwise. 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, regardless of Python version. * On Python 3.11+, 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*). _PIP_USE_IMPORTLIB_METADATAN) FrT) contextlibsuppressKeyError ValueErrorboolrosenvironsys version_infoimportlib.metadatagetattrmetadata importlibr%V/var/www/html/gsl.tools/lib/python3.9/site-packages/pip/_internal/metadata/__init__.py_should_use_importlib_metadatas 0 r'c@s&eZdZUeeed<eeed<dS)Backend Distribution EnvironmentN)__name__ __module__ __qualname__rr __annotations__r r%r%r%r&r(4s  r()maxsizecCs2trddlm}tt|Sddlm}tt|S)Nrr#) pkg_resources)r'r$rr(r0)r$r0r%r%r&r9s    rcCs tjS)a Get the default representation for the current environment.
