Django-CMS : Неожиданный аргумент ключевого слова 'providing_args'

Я установил ванильный django-cms на новый сервер. Я установил все требования. Все шло хорошо, вплоть до того момента, когда я хотел мигрировать на базу данных (Postgres).

Вот что я сделал :

  1. Tried reinstalling and installing it all again. Didn't change it.
  2. Used google to try and find people with the same error.
  3. Try editing the signals file on which the error(shown below) fires, but that meant rewriting it all, which still made it unresponsive.

Traceback:

У кого-нибудь есть идеи? Я что-то упустил. Спасибо за ваше время!

Аргумент providing_args для django.dispatch.Signal удален. Необходимо найти новые решения.

Я нашел ответ на эту проблему. Если вы посмотрите на документацию по Django. Это был Django от 2.0 до 3.0.

Делать раньше :

pizza_done = django.dispatch.Signal(providing_args = ['toppings'])

теперь это: 

Defining signals

All signals are django.dispatch.Signal instances.

For example:

import django.dispatch

pizza_done = django.dispatch.Signal()
This declares a pizza_done signal.

Обновление django-cors-headers на python -m pip install -U django-cors-headers решает эту проблему.
