我按照https://update.angular.io/中给出的步骤进行操作. 升级到Angular 6后,应用程序显示所有路径的空白屏幕.并且浏览器控制台中也没有显示错误.每个路由重定向到默认路径http:// localhost:4200.但http:// localhost:4200/admin工作正常.
任何人都可以帮忙,可能是什么问题？您需要我提供哪些信息才能重现问题？

一旦我从Angular 5更新到6,我遇到了同样的问题.
我发现Angular在我的应用程序中根本没有加载,我甚至没有得到消息" Angular is running in the development mode. Call enableProdMode() to enable the production mode."经过一些挖掘我注意到Angular 6生成的文件之一是不同的.产生之前,它inline.js,polyfills.js,scripts.js,vendor.js和main.js.从Angular 6开始,它现在生成runtime.js而不是inline.js.我一直在使用Angular和MVC,所以我直接引用了输出文件.我将引用更改inline.*为runtime.*(对于MVC而言BundlesConfig.cs),所有内容都是正确的.
生成的文件应生成,/dist/除非您更改了此项.您可以在angular.json下面确认路径projects -> my-project-name -> architect -> build -> options -> outputPath.
升级的另一个问题可能与您的问题有关,因为我的css文件不再生成,因为ng build的-ec参数不再适用于Angular 6; 你现在必须使用--extract-css.
希望有所帮助.
