[Pydev-users] [Users] PYTHONPATH

Hi,
I am using Eclipse Indigo, python3.2 from macports on a macbook pro with lion.
Trying to run a simple one line program like - print('hi') - gives the traceback
below.
It seems to me that the 'from collections ...' in functools should be not be
resolved through matplotlib?
The output following 'searching' stems from a print(PYTHONPATH) which I added
to site.py.
Following the traceback is some output from python interpreterinfo.py
Please help. Deleting the python interpreter for the project and adding a new
interpreter and pythonpath does not change the printed pythonpath in a way I
would expect.

The following forum message was posted by fabioz at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4834958:

It does seem weird that the collections imported is not the one from Python.
Does it work from the command line?

Can you run:

import sys
print('\n'.join(sorted(sys.path)))

From both the command line and Eclipse (to try to discover if there's any difference
there).

Cheers,

Fabio

Hi Fabio, 

running as you proposed
import sys
print('\n'.join(sorted(sys.path)))
from the command line gives:

The following forum message was posted by fabioz at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4834958:

It seems you ran different things from within Eclipse (I can read what you got
from the command line, but it's pretty hard to parse what you've run from
Eclipse

Please run:

import sys print('\n'.join(sorted(sys.path)))

from Eclipse and post the results again.

Note: from a quick look, I believe you're adding
/opt/local/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/site-p
ackages/matplotlib to the PYTHONPATH, and this directory should NOT be added
(you're putting the internal stuff on matplotlib in the PYTHONPATH).

Cheers,

Fabio
