Question

我已经在Stackoverflow中阅读了问题并使用Google搜索，但没有运气。

我正在尝试在pycharm中创建一个超级用户（manage.py createsuperuser ）但得到以下错误：

＆＃34; cassandra.protocol.SyntaxException：＆＃34;

Not checking migrations as it is not possible to access/create the django_migrations table.

我做错了什么？

我使用的是Cassandra 3.0，Python Django 1.11.4和pycharm。

我们不能使用：使用Cassandra的python manage.py createsuperuser它不能与默认的django模型一起使用。您需要使用外部库。用户模块默认情况下不适用于Cassandra

请阅读data-stax或以下给定链接的文档。 https://pypi.python.org/pypi/django-cassandra-engine/
