由于错误，预渲染失败：ReferenceError：未定义窗口

Question

我是Angular2的新用户，我正在尝试使用演示项目进行功能，并在代码中使用Webpack进行预渲染。

我的代码在这里 -

https://github.com/abrarjahin/Dot.NetCore_Angular2_App

我收到此错误 -

An unhandled exception occurred while processing the request.

Current directory is: D:\Dot.NetCore_Angular2_App\ProfileManagement 

我的代码中从未使用任何窗口。

有没有人知道我为什么会收到这个错误？

重新 -

我检查了这个问题 - AngularJS ReferenceError: $window is not defined

但它没有帮助。

提前感谢您的帮助。

导入npm模块时遇到了同样的问题，我通过在Index.cshtml页面替换app组件的prerender属性来解决这个问题：

<app asp-prerender-module="ClientApp/dist/main-server">Loading...</app>

到

<app asp-ng2-prerender-module="ClientApp/dist/main-server">Loading...</app>

也许它可以帮到你。
