如何使Angular 8与IE11兼容? [英] How do I make Angular 8 compatible with IE11?

问题描述

我使用ng update升级到了Angular 8.它运行了迁移脚本，该脚本除其他外还删除了polyfills.ts中的es6/es7导入.根据我的阅读，Angular将为较旧的浏览器(包括IE11)创建一个特殊的版本，而我不必担心polyfills了吗?我将browserlist更新为not IE 9-10，而不是将not IE 9-11更改为(我认为)暗示它应该构建适当的polyfills.

I upgraded to Angular 8 using ng update. It ran its migration scripts which (among other things) removed the es6/es7 imports in polyfills.ts. From what I read, Angular will create a special build for older browsers (including IE11) and I don't have to worry about polyfills anymore? I updated browserlist to be not IE 9-10 instead of not IE 9-11 to (I presume) hint that it should build the appropriate polyfills.

不幸的是，运行ng build后，出现一些与polyfill相关的错误，例如. Reflect.getMetadata is not a function和Object doesn't support property or method 'includes'.我尝试将reflect和array导入放回polyfills中并克服这些错误，但是我遇到了其他错误.这是怎么回事?我应该包括polyfills吗?

Unfortunately, after running ng build, I get some polyfill related errors, eg. Reflect.getMetadata is not a function and Object doesn't support property or method 'includes'. I tried putting reflect and array imports back into polyfills and move past those errors, but I get others. What's the deal? Am I supposed to include polyfills or not?

推荐答案

让 IE 11 与 Angular 8 配合使用的一种方法是禁用差异加载.

One way to get IE 11 to work with Angular 8 is to disable differential loading.

执行以下操作:

1. 使用"target": "es5"
更新tsconfig.json
2. 使用import 'core-js'; // core-js@^3.1.4
更新polyfills.ts
