How to set up PYTHONPATH on Windows?

This FAQ applies to: 1.4.5

MGLTools is not installed in Lib\site-packages folder of your Python installation and you are getting an ImportError.

If you are getting ImporError messages similar to this one


ImportError: No module named Pmv

, you'll need to set PYTHONPATH Environment Variable to point to the location of MGLToolsPckgs.

To set the PYTHONPATH variable:

Go to Control Panel -> System-> Advanced.
Click 'Environment Variables' button.
In the 'System Variables' panel that appears, click New and enter PYTHONPATH in the 'Variable Name' field. In the 'Variable Value' field enter path to MGLToolsPckgs (e.g. C:\Program Files\MGLTools-1.4.5\MGLToolsPckgs).

Note that our standalone installer creates/modifies C:\Python24\Lib\sitecustomize.py to include the latest version of MGLToolsPckgs in your path.
