AngularJS与GoogleAPI服务

Question

我正在使用https://github.com/christiansmith/ngGAPI此服务帮助我获取Youtube的Google API Services V3。虽然我已经遵循指示。也有依赖性。但它不起作用。例如

angular
    .module('app', [
        "gapi"
    ])
  .value('GoogleApp', {
        apiKey: 'AIzaSyAm_1TROkfNgY-XYZABCDEGGHI',
        clientId: 'NUMBERS.apps.googleusercontent.com',
        scopes: [
            'https://www.googleapis.com/auth/drive',
            'https://www.googleapis.com/auth/youtube',
            'https://www.googleapis.com/auth/userinfo.profile'
        ]
    })
   .controller('YoutubeController', ['$scope', 'Video', "Youtube", "GAPI",
    function ($scope, Video, Youtube, GAPI) {
        GAPI.init();
        $scope.videos = Youtube.search({part: 'snippet', q: 'Sample Text to Search'})
    }]);

包含Google Apis链接。但它给我的错误是GAPI.app.oauthToken is undefined或某个时间gapi.auth is undefined请帮忙

我在本地服务器http://localhost:3000/#/
