Question

I can’t seem to get pip to uninstall a package when using the environment flag.

I’ve created a virtual environment:

virtualenv --no-site-packages /path/to/testenv

While not in the virtual environment, I issue:

pip install --environment /path/to/testenv django

Django is downloaded and installed.

If I do the same command in reverse, it doesn’t work:

pip uninstall --environment /path/to/testenv django

The uninstall command outputs:

Uninstalling Django: Proceed (y/n)? y
Successfully uninstalled Django

But if I actually go in to the virtual environment:
. /path/to/testenv/bin/activate

and then run the uninstall command:
pip uninstall django

I get:

Uninstalling Django:

/path/to/testenv/bin/django-admin.py
/path/to/testenv/lib/python2.7/site-packages/Django-1.3.1-py2.7.egg-info
/path/to/testenv/lib/python2.7/site-packages/django
Proceed (y/n)?

I’m running pip 1.0

Am I missing something, or did I hit a bug?

Answer 1

Appears to be a bug in pip 1.0. Seems to work if I pip install --upgrade pip and then try it.
