我仍然坚持：

cd twissandra
python manage.py sync_cassandra

python manage.py sync_cassandra将生成

是的，那是错误.. 但我有点困惑，sudo或不sudo ...
python manage.py sync_cassandra或sudo python manage.py sync_cassandra

Answer 1

解决。没有sudo是正确的。它将使用虚拟环境中的python版本

为Django设置Cassandra - “python manage.py sync_cassandra”或“sudo python manage.py sync_cassandra”
