Django + Nginx + uWSGI: Internal Server Error

Question

I'm getting an "Internal Server Error" when I try to GET my site. This is what's on the log file:

Tue May  9 02:46:31 2017 - spawned uWSGI worker 3 (pid: 12738, cores: 1)

And this is mys uWSGI config file:

[uwsgi]
project = landingpage
base = /home/ubuntu

chdir = %(base)/%(project)
home = %(base)/%(project)/venv/
module = %(base)/%(project).wsgi:application

logto=/var/log/uwsgi/%(project).log

master = true
processes = 3

socket = /tmp/%(project).sock
chmod-socket = 664
vacuum = true

I honestly don't know what I'm missing here...

Answer 1

The error says:

ImportError: Import by filename is not supported.

Which leads to the line module = %(base)/%(project).wsgi:application , where you target the wsgi application with a unix filepath notation ( / ) instead of a python one ( . ).

Try module = %(project).wsgi:application

EDIT:

Additionally I had a problem, my module name was not my project's directory name.

I tried:

module = myrealmodulename.wsgi:application

And it worked!
