Angular AOT Build：内部错误：未定义的未知标识符

我目前的角度项目在角度支持AOT功能之前就开始了.现在我正试图让它发挥作用.我收到以下错误,我不知道这意味着什么,我可以开始调试问题.有谁知道为什么会出现这个错误？

解决方法

这部分应用程序导致了这个问题：

export function windowFactory(): any {
    return window;
}

providers: [{
    provide: Window,useFactory: windowFactory
}],

Github: This fails with AoT compiler in Angular CLI,because Window (the browser window) is an interface
