UWSGI not running django project out of the box?

Question

Django

Deploying a Django project on Nginx + uWSGI. I ran into a strange error, the wsgi test file starts up normally, but the dzhang one, which comes straight from the box, does not want to start for some reason.
Here is the content of the test file:

def application(env, start_response):
     start_response('200 OK', [('Content-Type','text/html')])
     return [b"Hello World"]

Here is the junga file:

import os

from django.core.wsgi import get_wsgi_application

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

application = get_wsgi_application()

traceback:

Traceback (most recent call last):
  File "wsgi.py", line 16, in <module>
    application = get_wsgi_application()

ModuleNotFoundError: No module named 'testproject'

I deploy the project in virtualenv, python version is 3.8.8.
I understand that it does not find the module of the project itself, but I do not know why. Help with good advice, please!

Answer 1

If suddenly someone has the same problem with python versions, then on ubuntu the versions are changed with the following command

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.8 1

Answer 2

You run not through a virtual environment, but really in a real system, and, of course, there is nothing there. You need to run something like this: .venv/bin/python myscript.py
By the way, you can also install packages on the environment like this: .venv/bin/pip install django
But this is for the normal launch of one command without activating the environment.
As for the server, try reading this:
Nginx + uWSGI + virtualenv + Django | Recipes | DJ...

Answer 3

UWSGI runs a django project out of the box. And now see what python you have in traceback.
