[Python-modules-team] Bug#945214: python3-pip: pip3 list AttributeError: _version

[Sebastien KALT]

Package: python3-pip
Version: 18.1-5
Severity: grave
Justification: renders package unusable

Dear Maintainer,

I think I have this error on Debian Sid since the 6th of november and
python3.8 / python3.8-minimal / python3.8-stdlib install

$ pip3 list
Exception:
Traceback (most recent call last):
  File "/usr/share/python-wheels/pkg_resources-0.0.0-py2.py3-none-
any.whl/pkg_resources/__init__.py", line 2649, in version
    return self._version
  File "/usr/share/python-wheels/pkg_resources-0.0.0-py2.py3-none-
any.whl/pkg_resources/__init__.py", line 2756, in __getattr__
    raise AttributeError(attr)
AttributeError: _version

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_internal/cli/base_command.py", line
143, in main
    status = self.run(options, args)
  File "/usr/lib/python3/dist-packages/pip/_internal/commands/list.py", line
145, in run
    self.output_package_listing(packages, options)
  File "/usr/lib/python3/dist-packages/pip/_internal/commands/list.py", line
210, in output_package_listing
    data, header = format_for_columns(packages, options)
  File "/usr/lib/python3/dist-packages/pip/_internal/commands/list.py", line
276, in format_for_columns
    row = [proj.project_name, proj.version]
  File "/usr/share/python-wheels/pkg_resources-0.0.0-py2.py3-none-
any.whl/pkg_resources/__init__.py", line 2654, in version
    raise ValueError(tmpl % self.PKG_INFO, self)
ValueError: ("Missing 'Version:' header and/or PKG-INFO file", testpath
[unknown version] (/usr/lib/python3/dist-packages))

But apt-get purge python3.8-stdlib python3.8-minimal python3.8 doesn't resolve
this problem, so it might be unrelated.

Regards,

Sébastien KALT
