error in GDAL setup command: use_2to3 is invalid

I'm trying to deploy my GeoDjango app to Heroku.

First of all, I'm using the pack and followed the instructions.

I got the mentioned error and tried to search for answers. I took a look at this one

and tried but the same error comes up every single time. The project is built on Python 3.7.10 - I even tried this answer and changed the Python version to 3.9.13 - but nothing.

I get this error _"error in GDAL setup command: use2to3 is invalid."

Additionally, it says Numpy not available but I later installed it and refreshed the requirements.txt file.

### The error I get in detail:
