mod_wsgi cannot be loaded as Python module

Question

I'm trying to access a Django application using apache and I'm getting Internal Server Error. I've opened the logs to see what is going on and I found this:

[Thu Jun 23 03:10:03 2016] [notice] suEXEC mechanism enabled (wrapper:  /usr/sbin/suexec)

I'm using python 3.4, Django 1.9, apache 2.2. and here is my apache configuration:

WSGISocketPrefix /var/run/wsgi
WSGIScriptAlias / /home/TaskManagement/teamwork/wsgi.py process-group=hrm.jodod.info
WSGIDaemonProcess hrm.jodod.info python-path=/home/TaskManagement:/home/py3venv/lib/python3.4/site-packages
WSGIProcessGroup hrm.jodod.info

Alias /robots.txt /home/TaskManagement/robots.txt
Alias /favicon.ico /home/TaskManagement/favicon.ico
Alias /static/ /home/TaskManagement/static/

<Directory /path/to/mysite.com/static>
Order deny,allow
Allow from all
</Directory>

<Directory /home/TaskManagement/teamwork>
<Files wsgi.py>
Order deny,allow
Allow from all
</Files>

and here is my wsgi.py file:

import os
import sys

sys.path.append('/home/TaskManagement')
sys.path.append('/home/TaskManagement/teamwork')
from django.core.wsgi import get_wsgi_application

os.environ["DJANGO_SETTINGS_MODULE"] = "{{ project_name }}.settings"
application = get_wsgi_application()

Can anybody figure out what am I doing wrong?

Python/2.6.6 configured -- resuming normal operations

Looks like your mod_wsgi is compiled against Python 2.6.6 and you're trying to run Python3 code with it. The Set syntax you are seeing in the error appeared in Py3. Recompile mod_wsgi and try again.

This was the problem. I had to install the source of mod_wsgi and compiled it against python 3.4 and it worked.

Your wsgi.py line 9 has to be

os.environ["DJANGO_SETTINGS_MODULE"] = "teamwork.settings"

if the directory it's stored is called teamwork (your project's name)

also in your manage.py it has to be "teamwork.settings"

You can't use Django's template syntax within python files
