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：

}
}
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。
