ModuleNotFoundError: "No module named <mymodule>", when deploying to Heroku from Django

Question

When deploying my Django app to Heroku, I get a ModuleNotFoundError that states "no module named 'RealisticEstate'". RealisticEstate is the name of my Django project. The program builds no problem, but when I try to deploy I get the following errors:

9:35:45 PM web.1 |  ModuleNotFoundError: No module named 'RealisticEstate'

My Procfile is as follows:

web: gunicorn RealisticEstate.wsgi

My Heroku project is named "realisticestate", but when I tried changing my Procfile to:

web: gunicorn realisticestate.wsgi

it throws the same error.

Here is the project structure:

RealisticEstate
|___config
|   |___static
|   |   |___admin
|   |       |___css     
|   |       |___font
|   |       |___img
|   |       |___js
|   |___ __init__.py
|   |___ asgi.py
|   |___ settings.py
|   |___ urls.py
|   |___ wsgi.py
|
|___mapper
|   |___ migrations
|   |___ utils

|   |   |___ update_db.py
|   |___ __init.py__

|   |___ staticfiles
|
|___ templates
|___ venv
|___ .gitignore
|___ manage.py
|___ models.py
|___ Procfile
|___ requirements.txt

Any help would be greatly appreciated

Answer 1

Only what's inside the git root directory ( RealisticEstate ) will be pushed to Heroku, not the directory itself. Your wsgi file is then config/wsgi.py therefore you should use:

web: gunicorn config.wsgi

Answer 2

it is true that you need to put project_name in your Procfile, and that because always the folders wraping all the folder have the same name of the folder where wsgi.py exists.wich your Procfile should point to,but in your case you named it config so it should be:

web: gunicorn config.wsgi 

i personally add it like this:

web: gunicorn config.wsgi --log-file -
