问题描述
我是 Angular2 的新手，我正在尝试通过演示项目进行功能测试并使用预渲染在代码中使用 Webpack .
I am new in Angular2, I am trying to go through functionalities with a demo project and used prerendering with Webpack in the code.
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.
Exception: Call to Node module failed with error: Prerendering failed because of error: ReferenceError: window is not defined

我从未在代码中使用任何窗口.
I never used any window in my code.
有人知道为什么我会收到此错误吗?
Does anyone have any idea why I am getting this error?
我已经检查了这个问题- AngularJS ReferenceError:未定义$ window
I had checked this question - AngularJS ReferenceError: $window is not defined
但这没有帮助.
预先感谢您的帮助.
推荐答案
导入npm模块时，我遇到了同样的问题，我通过替换Index.cshtml页面上应用程序组件的prerender属性来解决此问题:
I had the same issue when import npm modules, I fixed this by replacing prerender attribute for app component at Index.cshtml page:
<app asp-prerender-module="ClientApp/dist/main-server">Loading...</app>
到
<app asp-ng2-prerender-module="ClientApp/dist/main-server">Loading...</app>
也许对您有帮助.
