ModuleNotFoundError: No module named 'games.wsgi' when deploying Django app to heroku

Question

I'm trying to deploy a Django app to heroku. I get an error of ModuleNotFoundError: No module named 'games.wsgi' where games is my project name. My Procfile created is web: gunicorn games.wsgi . I have installed gunicorn. My requirements.txt is

asgiref==3.3.4
Django==3.2
gunicorn==20.1.0
pytz==2021.1
sqlparse==0.4.1

and pipfile also has [packages] gunicorn = "*" my wsgi file has os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'games.settings')

my heroku logs show

Can someone help I have been trying to figure out but everything seems to be correct but still I'm getting this error

Answer 1

Probably it's about Python path. Had the same problem on Centos8.

Simply changed PYTHONPATH to the directory wsgi.py is in.
In case of Linux it would be export PYTHONPATH='D/games/games'.
If you use IDE, you can manage PYTHONPATH from IDE settings.

Then step one level upper to 'D/games' and then try gunicorn games.wsgi:application .

idk how to change pythonath on Windows but seems this article is all about it: How to add to the PYTHONPATH in Windows, so it finds my modules/packages?
