Angular 6应用程序无法在IE <11中运行

Question

我的Angular应用程序不能在低于11的IE中运行，但是以前它甚至不能在IE 11中运行，但是在取消对polyfills.ts中的某些导入进行注释后，它仍然有效，但是在较低版本中仍然存在该问题。

分别是我的polyfills.ts，package.json和浏览器控制台错误

polyfills.ts

/**
* 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

IE 10中的

控制台错误

，对于IE 9控制台为空。

请提出可能的解决方案。

Answer 1

面对Angular 6的相同问题。只有取消注释的Pollyfills根本不起作用。 除了它之外，还可以在您的index.html文件中添加元标记 <meta http-equiv="X-UA-Compatible" content="IE=edge" > 。

Answer 2

首先在IDE或文本编辑器中打开文件：ie-test \ src \ polyfills.ts 取消注释其中的所有导入行。或者只是替换所有 //导入 与 导入

安装2个软件包 npm install-保存classlist.js npm install --save web-animations-js
