我尝试在Internet Explorer 11中运行由angular-cli 1.0.0构建的我的处女Angular 4应用程序，但是我没有成功，我收到以下错误：

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。在谷歌浏览器中它完美运行。
我的package.json：

  "ng": "ng","start": "ng serve","build": "ng build","test": "ng test","lint": "ng lint","e2e": "ng e2e"

}
}

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 polyfill，事情应该可以顺利进行。
