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，并且出现以下错误：

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：

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

 * 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';

取消注释该文件中的所有 IE polyfills，一切都会顺利进行。

IE 11 需要 ES6 polyfill。因此，您必须为所需的 polyfill 添加脚本标签，以便您的应用程序在 IE11 上运行。

有关浏览器支持的指导，请参阅文档。
