HTML

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script>
<script type="text/javascript" src="http://cdn.jsdelivr.net/restangular/latest/restangular.min.js"></script>
<script src="app.js"></script>
<script src="controllers.js"></script>

app.js

var contactManager = angular.module('contactManager', ['restangular'])
contactManager.config(function(RestangularProvider){
    RestangularProvider.setBaseUrl('/api/');
})

Answer 1

您需要添加脚本引用到下划线，因为是依赖项

 <script src="https://cdn of underscore"></script>

Answer 2

restangular需要下划线/ lodash`才能工作。把这个依赖放在你的restangular脚本之前。另请阅读this comment on github。

Answer 3

您需要在html文件中添加underscore.js的引用。您可以使用以下cdn路径：

<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.4.4/underscore-min.js"></script>

Answer 4

可能，您应该添加以下.js文件： -

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.8/angular.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.8/angular-resource.js">
</script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.8/angular-route.js">
</script> 
<script src="http://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.4.4/underscore-min.js">
</script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/restangular/1.5.1/restangular.js">
</script>
