Package: python-virtualenv
Version: 1.11.6-2
Severity: important
Dear Maintainer,
(I am unsure if this is because of interaction of pip with the virtualenv,
so I am reporting against python-virtualenv, not python-pip. Feel free
to reassign!)
When creating a virtualenv, the version of pip that gets installed does
not properly uninstall some packages. Consider the following script:
----------------->pip_fail.sh>-------------------
#!/bin/sh
set -x
unset PIP_DOWNLOAD_CACHE
virtualenv some_venv
. some_venv/bin/activate
pip install six==1.4.1
pip uninstall -y six
pip freeze
ls -la $VIRTUAL_ENV/lib/python2.7/site-packages/
ls -la $VIRTUAL_ENV/lib/python2.7/site-packages/six*egg*
cat $VIRTUAL_ENV/lib/python2.7/site-packages/six*egg*/installed-files.txt
rm -rf some_venv
-----------------<pip_fail.sh<-------------------
On my system, the uninstall fails with
Can't uninstall 'six'. No files were found to uninstall.
The installed-files.txt looks allright:
+ cat
/tmp/some_venv/lib/python2.7/site-packages/six-1.4.1-py2.7.egg-info/installed-files.txt
../six.py
../six.pyc
./
top_level.txt
dependency_links.txt
SOURCES.txt
PKG-INFO
Replacing 'six==1.4.1' with 'six==1.5.1' in the script above, the
uninstall completes without error. The obvious difference is that
six==1.5.1 uses a wheel, six==1.4.1 doesn't. Installing pip from pypi,
while keeping six==1.4.1, also fixes the problem:
----------------->pip_win.sh>--------------------
#!/bin/sh
set -x
unset PIP_DOWNLOAD_CACHE
virtualenv some_venv
. some_venv/bin/activate
pip install pip==1.5.4
pip install pip==1.5.6
pip install six==1.4.1
pip uninstall -y six
pip freeze
ls -la $VIRTUAL_ENV/lib/python2.7/site-packages/
ls -la $VIRTUAL_ENV/lib/python2.7/site-packages/six*egg*
cat $VIRTUAL_ENV/lib/python2.7/site-packages/six*egg*/installed-files.txt
rm -rf some_venv
-----------------<pip_win.sh<--------------------
Output of both scripts below.
Thanks,
Alex
