gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>

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:

Traceback (most recent call last):
  File "/home/ymorin007/.virtualenvs/onbytes.com/bin/gunicorn", line 9, in <module>
    load_entry_point('gunicorn==19.0.0', 'console_scripts', 'gunicorn')()

gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>

running gunicorn onbytes.wsgi:application --preload will get me this 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
