Nginx – ubuntu + nginx + uwsgi + django No Python application found

I am trying to setup my server with a nginx to uwsgi to django stack, but I am having problems with the uwsgi part.

When I run uwsgi and pass in all the parameters on the command line, it works properly. My uwsgi call looks like this:

uwsgi --socket /tmp/uwsgi.sock --chdir ~/web/test.com --wsgi-file ~/web/test.com/store/wsgi.py --virtualenv ~/web/test.com/testenv --chmod-socket=666 --enable-threads

I then copied those parameters into an ini file that looks like this:

# django.ini file
[uwsgi]
master          = true 
socket          = /tmp/uwsgi.sock
chmod-socket    = 666
chdir           = /home/ubuntu/web/test.com
wsgi_file       = /home/ubuntu/web/test.com/store/wsgi.py
virtualenv      = /home/ubuntu/web/test.com/causumptionenv
vacuum          = true
enable-threads  = true

However, when I run uwsgi with the django.ini file, I get this output.

Most notable are the lines "no app loaded. going in full dynamic mode and no python application found, check your startup logs for errors

So my question is, whats the difference between passing the parameters on the command line and passing them through an ini file?
