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?

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.
