[Python-modules-team] Bug#878082: python3-pip: TypeError: unorderable types: Version() > SetuptoolsVersion()

[Laurent Bonnaud]

Package: python3-pip
Version: 9.0.1-2
Severity: normal


Dear Maintainer,

here is the problem:

$ pip3 list --outdated
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
Exception:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/basecommand.py", line 215, in main
    status = self.run(options, args)
  File "/usr/lib/python3/dist-packages/pip/commands/list.py", line 157, in run
    packages = self.get_outdated(packages, options)
  File "/usr/lib/python3/dist-packages/pip/commands/list.py", line 168, in get_outdated
    dist for dist in self.iter_packages_latest_infos(packages, options)
  File "/usr/lib/python3/dist-packages/pip/commands/list.py", line 169, in <listcomp>
    if dist.latest_version > dist.parsed_version
TypeError: unorderable types: Version() > SetuptoolsVersion()

According to comments in this bug report:

  https://github.com/pypa/pip/issues/3057

the problem comes from Debian modifications to pip.
