问题描述
我将我的 Angular 项目从 5 更新到 6.但现在我在 Internet Explorer 11 上遇到了问题.每次我尝试在 localhost:4200 上加载实时开发服务器时，登录页面都会呈现，但会立即与实时开发服务器断开连接.
I updated my Angular Project from 5 to 6. But now I have issues with the Internet Explorer 11. Every time I try to load the live dev server on localhost:4200 the login page renders but immediatly disconnects from the live dev server.
所有其他浏览器都工作正常，控制台上没有错误(在 Edge、Firefox 和 Chrome 上尝试过)
All other Browsers work fine, no errors on the console (tried with Edge, Firefox and Chrome)
我的pollyfills看起来像这样:
My pollyfills look like this:
/**
* This file includes polyfills needed by Angular and is loaded before the app.
* You can add your own extra polyfills to this file.
*
* This file is divided into 2 sections:
* 1. Browser polyfills. These are applied before loading ZoneJS and are sorted by browsers.
* 2. Application imports. Files imported after ZoneJS that should be loaded before your main
* file.
*
* The current setup is for so-called "evergreen" browsers; the last versions of browsers that
* automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
* Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.
*
* Learn more in https://angular.io/docs/ts/latest/guide/browser-support.html

推荐答案
我实际上是通过从 index.html 中删除一个未使用的脚本来修复它的，因为我试图重现该问题.不知道是什么真正导致了问题，因为它只在我升级到 Angular 6 并且之前一切正常之后才持续存在.
I actually fixed it by deleting a unused script from my index.html as I was trying to reproduce the issue. No idea what was actually causing the issue for it persisted only since I upgraded to Angular 6 and everything was fine before.
