如题，在ie11下没有任何问题，但在ie9和ie10下，会直接报script1002:语法错误无从下手，也不知道该怎么处理，求大触们指导 v2 报错还是这个报错，但是偶然发现只有在ng serve时才会出现这个bug，ng build后的文件上传至服务器后可以正常打开，不会报错，但是比较奇怪的是，所有的(click)和*ngIf等用angular4的语法写出来的代码，就像失效了一样，包括一些表单的hasError方法，都会失效。一脸懵逼求大触指导

Run npm install --save intl.
Run npm install --save classlist.js.
然后找到src里面的polyfills.ts文件，将注释打开

/**
 * 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

PS:在IE9中，日期管道显示有问题(yyyy-mm-dd HH:mm:ss这种格式)，需要自己写一个日期的管道
