Answer 1

A simple pip install gunicorn resolved my issue.

I realised I deployed to Heroku and forgot to install gunicorn.

Dont forget to updated the requirements.txt file too

Answer 2

check Procfile if it contains your project name! if not, edit-

web: gunicorn your_project.wsgi --log-file

else;

pip install pipenv

Answer 3

this is where you error is

ImportError: No module named nmn.wsgi

you might be using an outdated package, try updating the package that is using nmn.wsgi

Answer 4

I have faced this error because of an error in wsgi.py module in this line. os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'django_project.settings')

Answer 5

In my case:

pip install django-heroku

in cmd prompt,

......................................................

then modified

django-heroku==0.3.1

in requirements.txt

......................................................

and the last, add

import django_heroku
django_heroku.settings(locals())

in very bottom in settings.py

Answer 6

A very simple solution I don't know how it works but its actually effective. Just install pipenv by typing the following in cmd pip install pipenv. After this try to push again and it will not crash.I hope it works.

Answer 7

Why you are refer gunicorn to nmn ( Is that actual project ).

gunicorn just needs to be called with the location of a module containing a WSGI application object named application

(i,e)

mysite
    -- mysite
           -- settings.py
           -- wsgi.py
           -- urls.py
    -- yourapp
           -- models.py
           -- admin.py
           -- views.py

So in your Procfile include this will work web: gunicorn mysite.wsgi --log-file -
