[Python-modules-team] Bug#892744: python3-pip: breaks with venv --system-site-packages

[Bernhard Reiter]

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

Hi Maintainers,

according to `pip help install`::

  --user
[..]
  On Debian systems, this is the default when running outside of a
  virtual environment and not as root.

However when using the recommended virtual environment `venv`,
the detection does not work. Example:

   python3 -m venv --system-site-packages x_env
   . x_env/in/activate.fish
   pip install vdirsyncer

will end up with installed files
in .local/bin and .local/lib/python3.5/site-packages/
While they should have been below x_env.

In https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=876145
the problems is also mentioned.

Best Regards,
Bernhard
