Re: ImportError: No module named nio

Hi Saulo,
Mary has the following suggestion:
It could be a path issue. Run python interactively and then type:

import sys
sys.path

to make sure that the directory containing Nio.pth is on your path. Also, Nio.pth needs to have just one line in it:

PyNIO

Hopefully you can find Nio.pth.
