I'm trying to deploy my Django project on Heroku, but something is going wrong, and I'm not able to found out what is happening, and what to do in order to solve this. I read in other posts that the problem may be something related with Gunicorn, but I can't solve it.

SOLUTION:

The problem was the location of my Procfile file: it has to be on the same path as manage.py. That's all!

Your gunicorn start command looks strange:

Starting process with command `gunicorn mysite.wsgi --log-file -`

The command should specify the module name and variable name separated with a colon, like this:

gunicorn mysite.wsgi:application

  • Still failling. I tried moving my Procfile inside the same path as manage.py, adding what you said, but still getting errors. This time, I got this, among other things `[2018-03-15 21:43:01 +0000] [4] [INFO] Starting gunicorn 19.7.1 2018-03-15T21:43:01.472311+00:00 app[web.1]: [2018-03-15 21:43:01 +0000] [8] [ERROR] Exception in worker process` – Ignacio Gazzaniga Mar 15 '18 at 21:53
  • Is the trace back exactly the same as before, or different this time? – Will Keeling Mar 18 '18 at 12:21
