[SOLVED] ERROR : No module named ""

I got a small problem using pylint to check my python code. I use the opencv library in my code, which results in

E: 85: Module 'cv' has no 'MoveWindow' member

errors in my code. The reason for that is explained here : http://www.logilab.org/blogentry/78354

So I did just as they asked and created an astng_cv.py file in my code. I updated my PYTHONPATH so that he knows where my file is.

But when I try :

pylint --load-plugins astng_cv eagle_road.py

I keep having a :

ImportError: No module named astng_cv

error.

This is quite annoying and I don't really know what to do to solve the issue.

Would you have an idea?

Thanks by advance !
