Question

I have the following code structure running perfectly fine in my IDE(Aptana Studio):

/ProjectName/
    /lib
    /src
        /Module1
        /Module2
        /Module3
         __init__.py
         pyClass.py         ##Python Class
        /main
         main.py

main.py :

import Module3.pyClass as pc

myClass=pc.pyClass()

but when I try to run it from command line , import error !

importError: No module named Module3.pyClass

I am running from the /main directory. Is it because it doesn’t know where to find Module3 to import?How should i tell where it should look for Module3 ?

Thank you.

The src directory isn’t in the python module search path if you run it from the main directory. You’ll need to either run the script from the src directory (a wrapper script, or move it) or add the src directory to sys.path. This is probably what you want. Here’s how:

import os
import sys
sys.path.append(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))

(If you’re compiling/freezing it with py2exe/py2app/cxfreeze/whatever, you’ll need a slightly different solution due to the way it works.)
