I also just found a different solution by using the Terminal and typing in: “launchctl setenv PYTHONPATH Path”
It works fine but now unfortunately I got a different problem. I use scripts written in Windows. Within this script the Python Imaging Library is used and a file called ‘_imaging.pyd’ is used. That gives me the following error: 'ImportError: cannot import name ‘_imaging’ ’
I think it is the problem that MAC os can’t handle a .pyd file? Do you have any idea how I can compile the file or a different solution?
