Javascript ngCordova和社交共享出错

错误：

HTML:

app.js

.controller('PlayCtrl', function($scope, $cordovaSocialSharing) {

  $scope.shareAnywhere = function() {
        $cordovaSocialSharing.share("This is your message", "This is your subject", "www/imagefile.png", "https://www.thepolyglotdeveloper.com");
  }

  $scope.shareViaTwitter = function(message, image, link) {
        $cordovaSocialSharing.canShareVia("twitter", message, image, link).then(function(result) {
            $cordovaSocialSharing.shareViaTwitter(message, image, link);
        }, function(error) {
            alert("Cannot share on Twitter");
        });
    }

})

因此，我使用（sudo npm install g-cordova）安装了cordova，并使用bower安装了ng cordova。我已经添加了socialshare插件，所有文件都位于我的ionic应用程序文件目录的插件文件夹中

我不知道要让它正常工作还需要做什么：（

检查你的文件夹树。ng-cordova.js实际上在“lib/ngCordova/dist”中吗？有时它会安装在其他与bower相关的目录中。是的，我检查了…我确实单独从github下载了cordova.js，但我将它放在了正确的位置。我是否需要在ios/andriod上构建cordova才能工作…因为我还没有。我正在做的一切都是在safari上测试

<!-- ionic/angularjs js -->
<script src="lib/ionic/js/ionic.bundle.js"></script>

<!-- cordova script (this will be a 404 during development) -->
<script src="lib/ngCordova/dist/ng-cordova.js"></script>
<script src="cordova.js"></script>

.controller('PlayCtrl', function($scope, $cordovaSocialSharing) {

  $scope.shareAnywhere = function() {
        $cordovaSocialSharing.share("This is your message", "This is your subject", "www/imagefile.png", "https://www.thepolyglotdeveloper.com");
  }

  $scope.shareViaTwitter = function(message, image, link) {
        $cordovaSocialSharing.canShareVia("twitter", message, image, link).then(function(result) {
            $cordovaSocialSharing.shareViaTwitter(message, image, link);
        }, function(error) {
            alert("Cannot share on Twitter");
        });
    }

})

angular.module('starter', ['ionic', 'starter.controllers', 'chart.js','ngCordova'])
