最近学习搭载一个简单的socket服务器 跟着教程学的 代码是照搬的 然而在cocos运行的时候报错 绝望！！！
Simulator: E/jswrapper (682): ScriptEngine::evalString script C:/Users/chelly/Documents/Cocos/STUDY/Client/assets/script/lib/socket.io.js, failed!
Simulator: E/jswrapper (272): ERROR: Uncaught ReferenceError: self is not defined, location: C:/Users/chelly/Documents/Cocos/STUDY/Client/assets/script/lib/socket.io.js:0:0
Simulator: iShow!
Simulator: E/jswrapper (682): ScriptEngine::evalString script main.js, failed!
求大神救命！！
