Django_celery_beat — нет модуля с именем «pymemcache»

У меня возникает странная проблема, когда я пытаюсь добавить задачу из пакета django_celery_beat на свой рабочий сервер. (В моем локальном рабочем пространстве все работает нормально).

Я получаю сообщение об ошибке «Нет модуля с именем pymemcache», но я уже установил его на свой venv.

На моем рабочем сервере у меня работает сервер memcached, и конфигурация следующая:

'default': {
            'BACKEND': 'django.core.cache.backends.memcached.PyMemcacheCache',
            'LOCATION': '10.100.23.95:11211',
        },

Как я могу решить эту проблему?

Большое спасибо за ваше время

Я попытался снова установить пакеты, но я не понимаю, что я делаю неправильно.
