windows virtualenv using global packages

I have the latest versions of virtualenv,django-nonrel, djangotoolbox and django_mongodb_engine. The virtualenv was created with -no-site-packages.

I attempted to follow the quick start but I see the following errors when trying to run syncdb

It appears to be trying to use the default django installation instead of my environments django-nonrel installation.

I have tried adding set PYTHONPATH=%PYTHONPATH%;C:\path\to\env\Lib\site-packages\django but no 开发者_如何学运维change.

Any ideas why the default django installation is being used here?

The problem was with the file associations under windows. I was trying to syncdb via "manage.py syncdb" which used the default windows python installation. Using "python manage.py syncdb" used the correct python and environment.

Have you tried running activate.bat?

Also, I think that setting PYTHONPATH should work, but you'd have to insert new path at the beggining, and it should be path to directory containing django instalation, not to django itself:

set PYTHONPATH=C:\path\to\env\Lib\site-packages\;%PYTHONPATH%

here are my 2 cents to this problem:

using PyDev as eclipse plugin, just pointing to new interpreter to be used with new project solves this issue.
