连接到Python 3.8中的Redis集群的AttributeError错误

问题描述

我正在尝试使用python 3.8中的RedisCluster模块连接到Redis集群。

redis-py-cluster==2.1.0

更新：添加ssl = True后，连接现在可以正常工作。

但是仍然存在引发AttributeError的问题。 rediscluster模块可能是这个错误吗？

  from rediscluster import RedisCluster

    _host = os.getenv('REdis_HOST')
    _port = os.getenv('REdis_PORT',6379)
    _password = os.getenv('REdis_PASSWORD')

    try:
      startup_nodes = [{"host": _host,"port": _port}]
      _redis_client = RedisCluster(startup_nodes=startup_nodes,decode_responses=True,ssl=True,password=_password)
    except Exception as x:
      print(x)

错误消息：
