Setting up django on apache (mod_wsgi, virtualenv) - django

Question

I'm putting my django site in production for the first time so please forgive for my ignorance.
I'm trying to put my django site on apache. I've read documentation about mod_wsgi and tried that simple Hello world so it is configured OK. The problem I'm having seems to be with using virtualenvs with it. I wanna set things up properly including virtualenvs and everything so I'm ready for future sites.
To the problem now.
The error I'm getting in apache log is:
No module named django.core.handlers.wsgi
So it seems that it is not reading my virtualenvs properly.
This is my wsgi script:
import os
import sys
import site
site.addsitedir('/home/user/.virtualenvs/myapp/lib/python2.7/site-packages')
path = '/home/user/django/myapp/myapp'
if path not in sys.path:
sys.path.append(path)
sys.stdout = sys.stderr
print sys.path
os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
And this is the error log from apache. I printed out the sys.path so you can see what it looks like.

If you have any suggestions or already had similar issue please help.
Thanks

Answer 1

You haven't added your actual virtualenv site-packages directory to the mix. Try:
import site
site.addsitedir('/path/to/your/virtualenv/lib/python2.X/site-packages')
# Where `X` is the specific version

Answer 2

For anyone that might have similar problem as I did. You need to check the whole path privileges to the directory where your virtualenv is stored.
I checked the home directory and changed privileges, but forgot to change privileges to my user directory and that fixed the thing.
Hope this helps.
