Dr. Bacon, запустил сервер. Надо было эти команды запустить по новой:

установка виртуального окружения, если его еще нет:
python -m venv venv

активирование вертуального окружения:
.\venv\scripts\activate

деактивация виртуального окружения:
deactivate

установка django в виртуальную среду:
(venv) c:\python\django-sites\django-premium>pip install django

создание корневой папки:
django-admin startproject testproject

запуск сервера:
-перейти в папку:   cd testproject
-запуск сервера:    python manage.py runserver
-остановка сервера: ctrl+c

создание проекта по имени venv:
(venv) c:\python\django-sites\django-premium>dango-admin startproject venv

запуск сервера:
(venv) c:\python\django-sites\django-premium\testproject>python manage.py runserver

Wolron, testapp.urls покажите.

Answer 1

[Los4inin]

Никто так и не решил проблему? Появилось то же самое после в старом проекте, возможно после обновления Питона с 3.8 на 3.11

Answer 2

[DoggieMurr]

можно посмотреть файл testapp/urls.py
