我按照 http://www.cocoachina.com/bbs/read.php?tid=196524 给的教材做了个例子，但是在运行的时候出现错误，如何修改
错误如下
cocos2d: iversion 1000
Assertion failed: (IsObject()), function FindMember, file /Users/hujiang/Documents/cocos/PrebuiltRuntimeJs/frameworks/runtime-src/proj.ios_mac/…/…/js-bindings/cocos2d-x/external/json/document.h, line 620.
下面两句注释掉可以运行，不注释掉出现上面的错误
var root = ccs.uiReader.widgetFromJsonFile(CocoStudio_index);
this.addChild(root,100);
以下是完整代码，app.js
var HelloWorldLayer = cc.Layer.extend({
isMouseDown:false,
helloImg:null,
helloLabel:null,
circle:null,
sprite:null,
ctor:function () {
//////////////////////////////
// 1. super init first

// 2. add a menu item with "X" image, which is clicked to quit the program
// you may modify it.
// ask director the window size
var size = cc.director.getWinSize();
// add a "close" icon to exit the progress. it's an autorelease object
var closeItem = cc.MenuItemImage.create(
res.CloseNormal_png,
res.CloseSelected_png,
function () {
cc.log("Menu is clicked!");
},this);
closeItem.attr({

this.addChild(menu, 1);

// add the label as a child to this layer
this.addChild(this.helloLabel, 5);
