ionic-framework - ionic2 Refresher 不显示 pullIcon 和 refreshIcon

Question

我正在开发 angularjs2/ionic2 移动应用程序，我需要集成刷新器以从本教程中进行刷新。刷新器工作正常，但我无法显示图标？这是我的代码：

<ion-refresher (starting)="doStarting()"
             (refresh)="doRefresh($event, refresher)"
             (pulling)="doPulling($event, amt)" 
              pullingIcon="ion-loading-c"
              pullingText="pull to refresh" 
              refreshingIcon="add" 
              refreshingText="loading" >
</ion-refresher>

这就是我得到的：

谁能帮我 ？

如果您希望它们出现，您必须设置这些属性：

"refreshingIcon" => the icon you want to display when performing a refresh
"refreshingText" => the text you want to display when performing a refresh
