在聊天信使中连接到redis-server时出错

Question

我用Python开发了一个聊天系统。已使用的库有:easygui、pycrypto、netifaces、stepic、redis、rabbitmq、pika、PIL和setuptools。所有的库都安装得很好参考: python>导入库通过在本地主机上使用redis-server，用户可以连接到redis并注册，登录，聊天，..但是当在不同的设备上设置redis并在代码中将localhost更改为redis服务器ip时，我收到以下错误。(我在oracle虚拟机中使用的是lubuntu最新版本)

enter code here
Traceback (most recent call last):

为了解决这个问题，我使用apt-get从系统中删除了之前安装的redis-server，并遵循以下链接说明：https://www.digitalocean.com/community/articles/how-to-install-and-use-redis
