How do I add a path to PYTHONPATH in virtualenv
python, virtualenv
Solution
You can usually avoid having to do anything with PYTHONPATH by using `.pth` files. Just put a file with a .pth extension (any basename works) in your virtualenv's site-packages folder, e.g. `lib\python2.7\site-packages`, with the absolute path to the directory containing your package as its only contents.
Problem
I am trying to add a path to the PYTHONPATH environment variable, that would be only visible from a particular virtualenv environment. I tried `SET PYTHONPATH=...` under a virtualenv command prompt, but that sets the variable for the whole environment. How do I achieve that?
