Import Error: AttributeError: module 'collections' has no attribute 'MutableMapping'

The attribute MutableMapping from the module collections got moved into collections.abc in python3.10.

In your case, /usr/share/python-wheels/pkg_resources-0.0.0-py2.py3-none-any.whl/pkg_resources/_vendor/pyparsing.py uses the MutableMapping attribute of collections.

If you can acces the source code, replace all collections.MutableMapping with collections.abc.MutableMapping.

An example :

import collections 
if sys.version_info.major == 3 and sys.version_info.minor >= 10:

    from collections.abc import MutableMapping
else:
    from collections import MutableMapping
