У меня проблема с Django urls.py досье. Когда я пишу python manage.py runserver , появляется эта ошибка:

 Exception in thread django-main-thread:

ModuleNotFoundError: No module named 'test_project.test_app'
 

Это происходит только с новыми проектами (проекты, загруженные с GitHub, работают просто отлично) и только после добавления пути в urls.py . Я просмотрел много основных потоков django на этом сайте, но ни один из них мне не помог.

urls.py

 from test_project.test_app.views import main_view

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', main_view())
]
 

Если я напишу from test_app.views import main_view , это покажет ошибку «Неразрешенная ссылка ‘test_app'».

settings.py УСТАНОВЛЕННЫЕ ПРИЛОЖЕНИЯ

 INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'test_app'
]
 

views.py

 def main_view(request):
    return HttpResponse("Why won't you work?")
