Question

我将Angular Project从5更新到了6。但是现在我的Internet Explorer 11出现了问题。每次尝试在localhost：4200上加载实时开发服务器时，都会显示登录页面，但立即与实时开发服务器断开连接

所有其他浏览器都可以正常工作，在控制台上没有错误（尝试使用Edge，Firefox和Chrome）

我的填埋场看起来像这样：

/**
 * 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

您错过了一条仍需要取消注释的评论：

/** IE10 and IE11 requires the following for the Reflect API. */
// import 'core-js/es6/reflect';

Answer 2

我实际上是在尝试重现此问题时，通过从index.html中删除未使用的脚本来修复它的。直到我升级到Angular 6之前一切都还好，才知道是什么真正导致了问题的发生。

加载到Angular 6 [WDS]后，在IE上断开连接
