为Django设置Cassandra-“；python manage.py sync“u cassandra”；或；sudo python manage.py sync_cassandra“；

我跟着导游走

我仍然被困在：

cd twissandra
python manage.py sync_cassandra

python manage.py sync\u cassandra

将生成

是的，那是错误。。

但是我有点困惑，

sudo

或者不是

sudo

。

python manage.py sync\u cassandra

或者

sudo python manage.py sync\u cassandra

解决了。没有

sudo

是正确的。它将使用虚拟环境中的python版本
