由 angular-cli 1.0.0 构建的 Angular 4.0.0 应用程序在 IE11 中不起作用 [英] Angular 4.0.0 App built by angular-cli 1.0.0 not working in IE11

问题描述

我尝试在 Internet Explorer 11 中运行由 angular-cli 1.0.0 构建的原始 Angular 4 应用程序，但没有成功并出现以下错误:

I try to run my virgin Angular 4 Application built by the angular-cli 1.0.0 in the Internet Explorer 11, but I have no success and I get the following error:

Error: The "apply" property of an undefined or null reference can not be retrieved.

我没有安装额外的库，它只是一个新生成的项目.在谷歌浏览器中，它运行良好.我的 package.json:

I have no additional library installed, it is just a new generated project. In Google Chrome it is working perfectly. My package.json:

推荐答案

Angular-CLI 在 src/目录中包含一个名为 pollyfills.ts 的文件.

Angular-CLI includes a file in the src/ directory called pollyfills.ts.

 * BROWSER POLYFILLS
 */

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/es6/symbol';
import 'core-js/es6/object';
import 'core-js/es7/object';
import 'core-js/es6/function';
import 'core-js/es6/parse-int';
import 'core-js/es6/parse-float';
import 'core-js/es6/number';
import 'core-js/es6/math';
import 'core-js/es6/string';
import 'core-js/es6/date';
import 'core-js/es6/array';
import 'core-js/es6/regexp';
import 'core-js/es6/map';
import 'core-js/es6/set';
import 'core-js/es7/array';

取消对该文件中所有 IE polyfill 的注释，一切都应该顺利进行.

Uncomment all of the IE polyfills in that file and things should work swimmingly.
