我在Angular JS接收错误时遇到问题：未捕获的错误：[$ injector：modulerr]。我的JS文件外观

angular.module('MyApp', ['ngRoute']);
angular.module('MyApp',['ngResource']);
function TwitterCtrl($scope,$resource){
}

我还包括了angular-route-js

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.7/angular.min.js">     
 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.7/angular-route.min.js">

Angular文档说问题出在http://docs.angularjs.org/api/ngRoute
