javascript - Angular 2 RC 4 "(SystemJS) Can' t 解析 [object Location] : "in IE 11 的所有参数

Question

我的 Web 应用程序在 Chrome、Firefox 和 Edge 中运行良好，但在 IE 11 中当然不行。可能也不是旧版本的 IE。它是一个使用 Angular Cli 生成应用程序的最小应用程序。

完整错误:

如您所见，我已经尝试了 es5-shim、es6-shim、IE shim、core-js shim 等的所有组合。似乎没有任何区别。

与LocationStrategy(HashLocationStrategy等)有关，定位策略存放在@angular/common包中。

检查你的 Bootstrap 代码，清除 IE 缓存，尝试重新安装包。
