我用Python开发了一个聊天系统。 库被使用：Easygui，Pycrypto，Netifaces，stepic，redis，Rabbitmq，pika，PIL和setuptools。所有库似乎都安装得很好，请参阅： python> 导入库通过使用本地主机上的Redis-Server，用户可以连接到Redis并进行注册，登录，聊天,..但是，当在不同的设备上设置 Redis 并在代码中将本地主机更改为 Redis 服务器 IP 时，我收到以下错误。（我在 Oracle 虚拟机中使用 Lubuntu 最新版本）

为了解决这个问题，我删除了之前使用 apt-get 从系统安装的 redis-server，并删除了以下链接指令：https://www.digitalocean.com/community/articles/how-to-install-and-use-redis
