[Python-modules-team] Bug#837169: Needs a versioned dependency on python-flake8

[Guido Günther]

Package: flake8
Version: 3.0.4+dfsg1-1
Severity: important
File: /usr/bin/flake8

Hi,
with flake8 and python3-flake8 2.5 installed I did a

    apt-get install flake8

which lead to:


$ flake8 --exclude="*rpm*" gbp/scripts/ tests/testutils/ gbp/deb/
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 635, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 943, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 834, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.VersionConflict: (flake8 2.5.4 (/usr/lib/python3/dist-packages), Requirement.parse('flake8==3.0.4'))

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/flake8", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2927, in <module>
    @_call_aside
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2913, in _call_aside
    f(*args, **kwargs)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2940, in _initialize_master_working_set
    working_set = WorkingSet._build_master()
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 637, in _build_master
    return cls._build_from_requirements(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 650, in _build_from_requirements
    dists = ws.resolve(reqs, Environment())
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 829, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'flake8==3.0.4' distribution was not found and is required by the application

after updating python3-flake8 as well everything was fine. So flake8
needs a tighter version dependency on python-flake8.

Cheers,
 -- Guido
