我按照《Nodejs实战》中第一张的案例编写代码，代码检查了几次，node也装了最新版本，运行server.js 的时候，但还是出现以下错误。
C:\Users\Administrator\Desktop\chatrooms>node server.js
C:\Users\Administrator\Desktop\chatrooms\node_modules\socket.io\lib\store.js:35
Store.prototype.__proto__ = EventEmitter.prototype;
^
TypeError: Cannot read property 'prototype' of undefined

提示是不能运行prototype,我贴一下关于prototype的代码吧。
var Chat = function(socket) {
this.socket = socket;
};
//添加发送聊天消息的函数
Chat.prototype.sendMessage = function(room, text) {
var message = {
room: room,
text: text
};
this.socket.emit('message', message);
};
//变更房间的函数
Chat.prototype.changeRoom = function(room) {
this.socket.emit('join', {
newRoom: room
});
};
//处理聊天命令
Chat.prototype.processCommand = function(command) {
var words = command.split(' ');
var command = words[0]
.substring(1, words[0].length)
.toLowerCase();
var message = false;
switch(command) {
case 'join':
words.shift();
var room = words.join(' ');
this.changeRoom(room);
break;
case 'nick':
words.shift();
var name = words.join(' ');
this.socket.emit('nameAttempt', name);
break;
default:
message = 'Unrecognized command.';
break;
}
return message;
};
谢谢你的回答。
