[Python-modules-team] Bug#813162: python3-pip: missing dependencies

[Sebastian Ramacher]

Package: python3-pip
Version: 8.0.2-1
Severity: serious

% pip3
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ImportError: No module named 'pip._vendor.cachecontrol'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
  File "/usr/lib/python3/dist-packages/pip/__init__.py", line 12, in <module>
    from pip.exceptions import InstallationError, CommandError, PipError
  File "/usr/lib/python3/dist-packages/pip/exceptions.py", line 6, in <module>
    from pip._vendor.six import iteritems
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 52, in <module>
    vendored("cachecontrol")
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 35, in vendored
    __import__(modulename, globals(), locals(), level=0)
ImportError: No module named 'cachecontrol'

After installing python3-cachecontrol, python3-lockfile, python3-packaging,
python3-progress and python3-retrying, pip3 no longer fails with ImportErrors.

Cheers
