JavaScript-TypeError：无法在IE 10上获取未定义或空引用的属性’ngMetadataName’

在IE 10中,出现以下错误：(但在IE 11中是正常的)

TypeError: Unable to get property ‘ngMetadataname’ of undefined or null reference

已在vendor.js中找到属性ngMetadataname.

polyfills.ts如下：

  /*******************************************************************************

*/
/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/es6/symbol';
import 'core-js/es6/object';

您能否建议如何解决IE 10的问题？

谢谢

解决方法:

我已经将angular-cli从6.0.8更新为6.2.3(最新),它解决了上述错误.

该链接github#24339可能会有所帮助.
