This is Mac related. I am running snow leopard. I am using Python 2.6.3.
I had a lot of difficulty figuring out how to add a directory to sys.path that
would be there every time I launched Idle. I have a directory called
PythonPrograms in my Documents folder. When I installed Python it had
'/Users/johnguenther/Documents' as sys.path[0]. I tried setting PYTHONPATH and
this worked for running Python from the bash shell but only until I exited the
shell. PYTHONPATH had to be reset each time I restarted the shell. And it had
no effect on sys.path when I ran Idle.
I tried putting files with names ending with .pth in various directories all of
which were already in sys.path. In this file I would put the path name of the
directory, i.e., '/Users/johnguenter/Documents/PythonPrograms'. This had
absolutely no effect.
I searched the web for help and found nothing that worked.
Finally I looked at a file that had been installed when I installed wxPython. I
modified that file and now the directory I want is always part of sys.path when
I start idle.
Since I had so much trouble finding an answer to the question "How do I
permanently change sys.path?", I thought I might post this message.
I created a file called myconfig.pth
In this file I included one line:
import site; site.addsitedir('/Users/johnguenther/Documents/PythonPrograms')
I placed the file in
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages.
