可能是什么问题？

根据，以下是两个服务器端初始化序列，应该可以正常工作：

var app = require('express')();
var server = require('http').Server(app);
var io = require('socket.io')(server);
server.listen(80);

或

您没有这两个选项。

您的客户端代码是什么样子的？我有'var server=http.createServer（app）；var io=require（'socket.io'）。侦听（服务器）；server.listen（config.port）；'
