我在打字方面遇到了一些问题.当我运行npm start时,我收到以下错误：

其他人在过去几个月里遇到过这个问题,但这些修复都没有对我有用.
有任何想法吗？ (Angular 2)
如果使用–target = es5,则需要在应用程序的某处添加一行(例如,在您调用bootstrap的.ts文件的顶部)：
<reference path="node_modules/angular2/typings/browser.d.ts"/>
看这篇文章：Angular 2 typescript can’t find names
我亲自切换到ES6,到目前为止完全正常.我还建议为Angular2做5min QuickStart和教程系列,因为你可以将它作为稳定的Skeleton用于进一步的项目：

祝好运
