module error in Vista -- works as administrator

sawilla

First, I'm new to Python. I'm getting and error when I run Python
2.5.2 as a regular user in Vista but not when I run Python as an
administrator.

For example, if I type "import numpy" after I launch python from an
adminstrator-privileged command window it loads fine. However, from a
regular-user command window I get:

>>import numpy

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named numpy

Thanks in advance for your help.

Log on as administrator, start python in command window and do this:

import sys
sys.path # shows where python is looking for importables
import numpy
import os.path
print os.path.abspath (numpy.__file__ ) # shows where it found numpy

Log on as ordinary user, start python in command window and do this:

import sys
sys.path
# check how this is different from the admin's sys.path

If you can't see what to do after that, come back here with the output
from those steps.

That was a great help, thank you. I now see what is causing the
problem but I don't know how to fix it. I used easy_install to install
several packages. When I run Python from an administrator command
window all of the directories in C:\Program Files\Python25\ Lib\site-
packages\easy-install.pth are added to the sys.path. When I run it as
a regular user, those directories are not added to the sys.path and so
Python can't find the modules.

I know how to manually add those directories to Python's search path
but then I'll need to update the path every time I install something.
How do I get Python to automatically load the easy-install.pth file
for the regular user account?

The access writes to easy-install.pth for regular users is read and
execute.

The output of sys.path for regular users is:

I've discovered the cause of the problem. At some point previously,
Windows Vista had created a copy of the site-packages directory in a
virtual store for the user account. The easy-install.pth file in the
virtual store did not contain the same path information as the easy-
install.pth that the administrator account sees. I deleted the user's
Python25 directory in the virtual store and now the user's sys.path
contains all of the necessary paths.
