Redis connection gone from end event.

我照着教程写了一遍一个博客，但是当注册的时候遇到了错误

Redis connection gone from end event.

Error: Redis connection gone from end event.
    at RedisClient.flush_and_error (D:\WebProgram\express-blog1\blog\node_modules\redis\index.js:149:13)
    at RedisClient.connection_gone (D:\WebProgram\express-blog1\blog\node_modules\redis\index.js:486:10)
    at Socket.<anonymous> (D:\WebProgram\express-blog1\blog\node_modules\redis\index.js:114:14)
    at Socket.EventEmitter.emit (events.js:117:20)
    at _stream_readable.js:920:16
    at process._tickCallback (node.js:415:13)

有没有人遇到过啊？能不能解答一下我的问题啊？
