Почему runserver не работает через django-admin, хотя работает через manage.py?

Question

[wawa]

Структура проекта:

mysite/
    - config/
        - settings/ [common.py, dev.py, prod.py]
        - urls.py
        - wsgi.py
        - __init__.py
    - manage.py

Через manage.py runserver работает, а через "python -m django runserver", "django-admin.exe runserver", "django-admin.py runserver" не работает.
Про DJANGO_SETTINGS_MODULE / --settings не забыл.
Выдает ошибку "ModuleNotFoundError: No module named 'config'"
Добавляю --pythonpath={полный путь к mysite} и уже получаю другую ошибку:
"ModuleNotFoundError: No module named 'http.cookies'"

P.S: да, я видел этот вопрос Почему не запускается сервер через django-admin?
и решение с --pythonpath по всей видимости помогло, но, как видите, возникла другая ошибка.

Comments

[Дмитрий Матвеев]

Зачем вообще использовать django-admin для запуска сервера? manage.py runserver рабочий и чаще всего используемый вариант.
P.S. За три года использования django первый раз о таком узнал)

[wawa]

Вы правы. Нет никакой необходимости не использовать manage.py.
Мною движет желание разобраться - почему не работает функционал, описанный в документации:

Generally, when working on a single Django project, it’s easier to use manage.py than django-admin. If you need to switch between multiple Django settings files, use django-admin with DJANGO_SETTINGS_MODULE or the --settings command line option.
-- https://docs.djangoproject.com/en/1.11/ref/django-... --

Что я делаю не так?

[Stanislav Pugachev]

пример того как вы запускаете через django-admin в студию
и вывод соответственно тоже

[wawa]

Stanislav Pugachev,
django-admin.exe runserver --settings=config.settings.dev --pythonpath="{путь к mysite}"
или
python -m django runserver --settings=config.settings.dev --pythonpath="{путь к mysite}"

Вывод (указывал выше):

wawa, win?

[wawa]

Максим, Win7 32bit / Python 3.6.3 / Django 1.11.11

[Максим]

wawa, добавьте в path django-admin

[wawa]

Максим, эффекта 0. Но все равно большое вам спасибо!
Через django-admin.EXE так и не запустил, а вот через умалчиваемый в доках версии >=1.8 старый добрый django-admin.PY всё ОК!
Ниже отписался о решении.

Answer 1

[wawa]

В общем так.
При помощи django-admin.exe и python -m django завести runserver не удалось.
По-моему это windows специфик проблема, но все-таки я запустил проект без manage.py.
Если посмотреть на доки версий >=1.8, то там используется django-admin (т.е. бинарник). Однако в более старых версиях использовался обычный django-admin.py, который сохранился и в версии 1.11. Вот через него всё работает:

path\to\venv\Scripts\activate.bat
python path\to\venv\Scripts\django-admin.py runserver --pythonpath=path\to\project_dir --settings=config.settings.dev
