How to set PYTHONPATH to multiple folders

Question

In ~/.bash_profile file (OS X) I've set PYTHONPATH to point to two folders:

export PYTHONPATH=/Applications/python/common:$PYTHONPATH export PYTHONPATH=/Applications/sitecustomize:$PYTHONPATH 

Even while sitecustomize folder is set on a second line (after /common) the first path is ignored and I am not able to import any module from the path defined in a first line. What needs to be revised in above syntax to make both folders PYTHONPATHish to Python?

Answer 1

Append your paths so there is only one PYTHONPATH.

PYTHONPATH="/Applications/python/common:/Applications/sitecustomize:$PYTHONPATH" export PYTHONPATH 

Then source ~/.bash_profile

OR import them into your Python script (this would only work for the script added to):

import sys sys.path.append("/Applications/python/common") sys.path.append("/Applications/sitecustomize")
