ModuleNotFoundError: Нет модуля с именем 'django_filters '

Когда я пытаюсь собрать все мои статические файлы в моем проекте в одном месте с помощью python manage.py collectstatic , я получаю сообщение об ошибке

ModuleNotFoundError: No module named ' django_filters

django_filters находится в моих настройках установленных приложений.

Есть идеи?
