express.js中未处理的'错误'事件

Question

var express = require('express');
var router = express.Router();

/* Socket.io */
var server = require("http").Server(express);  
var io = require("socket.io")(server);
server.listen(5000);
io.on('connection', function(client) {
  client.on('score_'+userId, function(data) {

  });
});

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Express' });
});

module.exports = router;

socket.io块导致错误，但我不知道为什么。代码对我来说很好。

Answer 1

使用var server = require("http").createServer(express());代替var server = require("http").Server(express);
