Я следовал учебнику по настройке приложения Django, но у меня возникли проблемы с применением тех же инструкций к моему собственному приложению.

Моя структура папок выглядит следующим образом:

 ├── project_name

 """
WSGI config for creativ_ceutical project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see

"""

import os

from django.core.wsgi import get_wsgi_application

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

application = get_wsgi_application()
 

Когда я запускаю start-server.sh сценарий, gunicorn не может породить рабочих из-за ModuleNotFoundError, в котором говорится «нет модуля с именем «имя_проекта»». Похоже, это связано с файлом wsgi, но я не понимаю, почему, поскольку в папке имя_проекта есть __init__.py файл, и я добавил его каталог os.sys.path . Полная обратная связь-это:
