我正在使用社交应用教程来学习Angular2和Meteor。我遇到了一个我找不到根本原因的问题。

我正在关注一个说明要添加的教程：

RouteConfig注解：

@RouteConfig([
  { 
    path: '/', 
    as: 'PartiesList', 
    component: PartiesList 
  }, { 
    path: '/party/:partyId', 
    as: 'PartyDetails', 
    component: PartyDetails 
  }
]);

router-outlet在 app.html 中：

<router-outlet></router-outlet>

在 Chrome 中加载应用程序时出现此异常：

EXCEPTION: Error in /client/app.html:0:0BrowserDomAdapter.logError @

如果我删除，@RouteConfig则不会发生异常，但没有任何内容明显显示，因为没有内容要呈现。知道是什么原因造成的吗？

一段时间后，角度时间和流星时间提出了新版本，在撰写本文时可以开箱即用。我还偶然发现了如何安装软件包。您可以使用以下格式：

meteor npm install @angular/core

例如安装角核心包

@RouterConfig 仅适用于不推荐使用的路由器和 rc1 的早期版本。随着新版本的发布，3.0.0.apha.7它不再可用。阅读Routing & Navigation上的文档

一个示例用法是

export const DashboarRoutes = [
  {
    path: 'dashboard',
    component: DashboardComponent
  },
  ...
  e.t.c      
] 
export const routes: RouterConfig = [
...DashboardRoutes,
...UIRoutes
];

export const APP_ROUTER_PROVIDERS = [
   provideRouter(routes)
];


APP_ROUTER_PROVIDERS is then passed when bootstrapping main application
