我一直在尝试使用我的python wepapp配置Redis群集（目前使用单个redis实例）
由于3.x支持redis群集，因此将redis服务器版本升级到3.0.7
在我的python应用程序中使用 redis-py-clusterV1.2.0 模块。
用于发布和订阅特定通道的PubSub命令似乎不适用于堆栈跟踪中提到的KeyError。如果有人可以提供帮助，那就太好了。
from rediscluster import StrictRedisCluster
startup_nodes = [{"host": "127.0.0.1", "port": "6379"}]
redis_conn = StrictRedisCluster(startup_nodes=startup_nodes,
decode_responses=True)
redis_conn.pubsub()
pubsub.subscribe(['a_b:c:d']) //tried with diff keys, getting the same error
错误的堆栈跟踪：

return self.nodes.slots[slot][0]

当我调试时，得知道self.nodes.slots []似乎是空的。没有线索为什么我得到这个错误。
先谢谢 普里亚
