iron-ajax找不到generateRequest（） - 方法

我是Polymer新手，嘗試通過iron-ajax創建ajax調用。我遇到了一個錯誤，generateRequest()未定義。iron-ajax找不到generateRequest（） - 方法

聚合物1正在使用中。

我安裝了鐵AJAX使用此命令：bower install --save PolymerLabs/promise-polyfill#1

正如你所看到的，我<link rel="import" href="../bower_components/promise-polyfill/promise-polyfill-lite.html">

加載它，我用一些例子進行比較，但不能發現其中的錯誤。有人有想法或解決方案嗎？

這是代碼：

您需要安裝iron-ajax：

bower install --save PolymerElements/iron-ajax

然後，您可以導入使用下面的代碼：

<link rel="import" href="../bower_components/iron-ajax/iron-ajax.html">

你的代碼將工作做完上述事情後。
