I've installed gunicorn inside my virtualenv.
From this directory:
manage.py
/onbytes/wsgi.py
I run the following:
gunicorn onbytes.wsgi:application
And I get the following error:

Probably there is an issue in your application, not in gunicorn.
Try:
gunicorn --log-file=- onbytes.wsgi:application
Since the version R19, Gunicorn doesn’t log by default in the console and the --debug option was deprecated.
Adding --preload the gunincorn command showed me that I had to do :
pip install ordereddict
That package was missing.
I had a similar problem and it was because i was running the command in the wrong directory. In a standard django installation, try running gunicorn in the same directory that 'manage.py'
in my case after adding --preload to Procfile, I understand that I should install psycopg2-binary with pip:
pip install psycopg2-binary
