pip tries to uninstall system packages

I'm using pip on webfaction and it keeps trying to uninstall system packages and then failing. For example if I try to install Fabric, one of the requirements is pycrypto. When it tries to uninstall it, it fails.

Is there anyway to tell pip to not do this?

My guess is you have created the virtualenv with the --system-site-packages option, so it could use some packages installed system-wide.

If that's indeed what you did, try to create a clean virtualenv, and install all your dependencies inside it. This way, you'll never have to think of what packages are installed sytem-wide and what packages are installed in the virtualenv.

To do so, you can use --no-site-packages, which has now become a default virtualenv option.

This is a common use scenario for virtualenv (aside from... all the time).

Build your app around a clean virtualenv so that you don't have to think about system packages ever again (mostly) in permission limited environments.
