[Python-modules-team] Bug#871790: python-pip-whl: pip freeze gives pkg_resources==0.0.0 in venvs

[Julien Palard]

Package: python-pip-whl
Version: 9.0.1-2
Severity: normal

Dear Maintainer,

When I run pip freez in a new venv, I'm getting "pkg-resources==0.0.0".

Here's how I reproduce it:
$ python3 --version
Python 3.5.3
$ python3 -m venv /tmp/pip-freeze
$ . /tmp/pip-freeze/bin/activate
(pip-freeze) $ python3 -m pip --version
pip 9.0.1 from /tmp/pip-freeze/lib/python3.5/site-packages (python 3.5)
(pip-freeze) $ python3 -m pip freeze
pkg-resources==0.0.0

I found this bug already reported here: https://bugs.launchpad.net/ubuntu/+source/python-pip/+bug/1635463 and I also opened an issue here: https://github.com/pypa/pip/issues/4668/.

I just expected a "pip freeze" to output nothing in a newly created venv.

It looks like pip freeze expect pkg_resource to be in setuptools, not
packaged separately. I searched a bit and can't find why it gets
separated from setuptools on Debian. I does *not* looks like a
"vendorized" version of something: it looks to lie in setuptools from
the beginning:
