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')()

    raise HaltServer(reason, self.WORKER_BOOT_ERROR)

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

Now 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.

To know more about this you can have a look at the following video:-
