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

was compiled successfully and I was able to get the output from the localhost. But now it is giving me this error. I tried following solution [ gunicorn app:application -b localhost:3000 ] that was stated in this thread #338. I was able to try just this one since I am not ursing django ,, i am using falcon as my web framework.

I see ImportError: No module named w. Is w the name of your application package? Have you installed your application correctly so that it's importable by gunicorn? Or are you launching gunicorn by pointing it directly at the .py file?

Can you show the full gunicorn command you use? Have you run other gunicorn applications successfully? Can you run your application with wsgiref or any other WSGI server?

[benoitc]

bump. doesn't look like a gunicorn error. Can you confirm?

[extremewaysback]

I got the same error. Find out that the root cause is an application which can't be installed through gunicorn. After disabling the related application in setting.py module, it works!

[benoitc]

an application which can't be installed through gunicorn

what do you mean by can't be installed? Did you set the python path correctly?

[extremewaysback]

It’s just a application I was testing something with, not complete. Forget to disable the application in INSTALLED_APPS of settings.py, so get the gunicorn errors I think. So after correcting this error, I deploy my app successfully.
