How to reset virtualenv and pip?

Question

I installed virtualenv on my Ubuntu 10.04 server.

Now when I do pip freeze it shows me the following packages:

Django==1.2.4
distribute==0.6.10
python-apt==0.7.94.2ubuntu6.2
virtualenv==1.5.1
wsgiref==0.1.2

When I do "pip uninstall Django" it says:

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

Ideally this should uninstall Django but it doesn't. I can still see the same packages when I do "pip freeze".

Now bear with me, the other weird thing is that when I create a virtualenv and then do "pip freeze" inside it, I see only one package and that is "wsgiref" which is weird because it should ideally be blank.

Also, in spite of creating this virtualenv with --no-site-packages I can still create a new django project with "django-admin.py startproject".

When I start python interpreter inside this virtualenv and do "import django" it gives me the error "No module named django".

Also when I try to install "pip install Django" inside the virtualenv it asks for sudo permissions which shouldn't happen ideally.

How do I sort out this mess. Any way to just reset everything pep and virtualenv?

Answer 1

As far as I can tell, the only purpose of a venv is to manage dependencies.

You should be safe to just deactivate the venv, delete it, and create a new one using virtualenv venv; source venv/bin/activate.

This will give you a fresh start.
