Bypass virtual python environments
Bypass virtual python environments

This change is intended to improve isolation by hiding packages installed in other virtual python environments.

It is also an attempt to fix #2.

Virtualenv does not support user site packages directories by default. There is some discussion about it here:

https://github.com/pypa/pip/issues/4141

By using the real python instead of a virtual one (which might be virtualenv) support for user site packages directories should be restored.
