Исключение django mongo db по команде syncdb

Question

Я использую django 1.5.5 с django-mongodb-engine version 0.5.1.

Я установил djangotoolbox с помощью следующей команды:

sudo pip install git+https://github.com/django-nonrel/djangotoolbox

В дистрибутивах Python, djangotoolbox версия 1.6.2,

Получение этой ошибки на syncdb command вызов.

Получил это решено.

Пожалуйста, смотрите эту ссылку для полной деинсталляции Django.

Удалить Django полностью

Правильное удаление django важно при обновлении до новой версии django.

Я снова установил django, используя django-nonrel, с помощью следующей команды:

sudo pip install git+https://github.com/django-nonrel/django@nonrel-1.5
