Django deployment to Heroku error: python: can't open file '/app/backend.manage.py':-CodePudding

I've once again come to beg stackoverflow for help. I am attempting to deploy a django project to Heroku and I'm getting slapped left and right with errors but hopefully this is the last one.

And when I try to run the program in a virtual environment on my local machine using the command heroku local:

6:06:35 PM web.1 |  [2022-03-07 18:06:35 -0400] [33412] [INFO] Starting gunicorn 20.1.0

And so on and so on.

I suspect this has to do with my Procfile. And admittedly, I'm not too sure on how to set it up. I currently have in my Procfile:

web: gunicorn --pythonpath backend.feh backend.feh.wsgi --log-file - 
release: python backend.manage.py makemigrations - - no-input

And my directory is setup via:

FE_APP/

runtime.txt
requirements.txt
Procfile
backend/
scraper.py

In FE_AP/backend/

__init__.py
api/
feh/
static/
db.sqlite3
manage.py

Where FE_APP/backend/feh/ has

__init__.py
errorlog
settings.py
urls.py
wsgi.py

I'm positive my Procfile is the cause for this issue but I don't know how to go about debugging this. At the very least, the project runs fine on my venv. Thank you in advance!

CodePudding user response：

Your release command refers to a file called backend.manage.py:

release: python backend.manage.py makemigrations - - no-input

That argument should be a path to a file, not a dotted Python module. I'm pretty sure you also want to use --no-input instead of - - no-input. Try this instead:

release: python backend/manage.py makemigrations --no-input
