Angular JS Uncaught Error: [$injector:modulerr]

I am having a problem with Angular JS receiving an error : Uncaught Error: [$injector:modulerr]. My JS-file looks

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

I also included 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 documentation says the problem is http://docs.angularjs.org/api/ngRoute

In development environments I recommend you to use not minified distributives. And all errors become more informative! Instead of angular.min.js, use angular.js.

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

Try adding this:

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

Try adding:

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

and:

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

You should call angular.module only once with all dependencies because with your current code, you're creating a new MyApp module overwriting the previous one.

From angular documentation:

Beware that using angular.module('myModule', []) will create the module myModule and overwrite any existing module named myModule. Use angular.module('myModule') to retrieve an existing module.
