How to add to the pythonpath in windows 7?

Question

Hi There,

I have a directory which hosts all my django app. *"C:\My_Projects".* I want to add this directory to my pythonpath so I can call the apps directly. I have *right clicked My Computer > Properties > Advanced System Settings > Environmental Variables. Then I added C:\My_Projects\; to my Path variable* but it still doesn't read the coltrane module. "Error: No module named coltrane"

Answer 1

You need to add to your PYTHONPATH variable instead of Windows PATH variable.

Answer 2

From Windows command line:

set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib

To set the PYTHONPATH permanently, add the line to your autoexec.bat. Alternatively, if you edit the system variable through the System Properties, it will also be changed permanently.

These solutions work, but they work for your code ONLY on your machine. I would add a couple of lines to your code that look like this:

import sys
if "C:\\My_Python_Lib" not in sys.path:
    sys.path.append("C:\\My_Python_Lib")

That should take care of your problems
