无法构建离子应用-AngularFire2构建错误

Question

我开始在我的离子应用中使用firebase。一切都起作用，我可以在浏览器中使用该应用程序。但是，每当我尝试使用命令ionic cordova build android构建Android的应用程序时，它都会显示一个构建错误如下：

Error: ./~/firebase/app/shared_promise.js
Module not found: Error: Can't resolve 'promise-polyfill' in 'D:mychatnode_modulesfirebaseapp'

这是我的软件包：

有什么建议？

正如@nickmcblain所建议的那样，我要做的就是安装 promise-polyfill，构建工作。
