我正在尝试编写单页应用程序,但是无法正常工作。我尝试使用许多教程,但考虑到Angular2仍处于测试阶段,它们似乎很快过时了。
看来,只要我添加对路由器指令或路由器配置或路由器提供程序的任何引用,该应用程序就会停止工作,并且在浏览器的控制台上会显示以下错误:

如果这是一个新手问题,很抱歉,但是从昨天开始我就一直坚持这个问题,而且我不知道该怎么解决...
确保router.dev.js
(包含)app/main.js
正确的位置。
您在这里错过了几件事。
base
与href="/"
标记您的网页上一样<base href="/">
<router-outlet></router-outlet>
指令useAsDefault: true
用于您指定的路线请在下面更改路线
@RouteConfig([
{ path: '/', component: Home, as: 'Home', useAsDefault: true }
])
