function MyController($scope,$firebase){
var ref= new Firebase('https://alpha-db.firebaseio.com/');

最佳答案
您放错了引用文献的顺序，您应该加载 firebase.js加载之前 angularfire.min.js 。将顺序更改为
<script src='lib/angular.min.js'></script>
<script src='lib/firebase.js'></script>
<script src='lib/angularfire.min.js'></script>
<script src='js/app.js'></script>
