ModuleNotFoundError: No module named 'wsgi'

Question

I was going to host it using Heroku. But it does not work because of the problem with the profile.

This my Procfile

-> web: gunicorn wsgi:app

I tried these things.

->web : gunicorn wsgi.py
->web : gunicorn <myproject>.wsgi --log-file-

my wsgi.py code

"""
WSGI config for config project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/2.2/howto/deployment/wsgi/
"""

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'config.settings')

application = get_wsgi_application()


from whitenoise.django import DjangoWhiteNoise
application = DjangoWhiteNoise(application)

this is my heroku log

Answer 1

web: gunicorn wsgi:app

This almost certainly isn't correct.

The arguments passed to gunicorn tell it where your application's entry point is. It matches your Python module path. Typically, this would be the file called wsgi.py inside your project directory:

myproject/
    wsgi.py

Therefore your Procfile should contain

web: gunicorn myproject.wsgi

Make sure to follow this format exactly. There shouldn't be a space between web and :.

Answer 2

My 2c for people reading in the future

I had exact same issue,

web: gunicorn wsgi:app

expects that the wsgi.py file is in the project root, ie MyProject/ wsgi.py

but I had it in

MyProject/ app / wsgi.py

for which the correct command would (confusingly) be:

web: gunicorn app.wsgi:app
