'Error: While importing 'wsgi', an ImportError was raised. Python Flask Ubuntu 20.04

I am building a backend using Python and Flask, everything worked fine, but after some updates on the Pipfile (updated some packages) I got this error when I try to run the app (flask run):

Error: While importing 'wsgi', an ImportError was raised.

Environment:

  • Ubuntu 20.04
  • Python 3.8.5
  • Flask 2.0.2
  • pipenv 2020.8.13
  • pip 21.2.4

Also, I tried with pyenv 1.2.21

I tried to run the backend in VSC but got the same error. Also, I tried to remove the interpreter and set it up again, remove Pipfile.lock, and pipenv install again... I have googled but found nothing about this error.

Thanks in advance!

Add the file __init__.py to the application directory

Try python wsgi.py and check output, maybe you should install additional requirements.
