angular - 错误 : Cannot find primary outlet to load 'ProfileDetailsComponent'

Question

我正在尝试在我的应用程序中使用路由，使用路由器版本 3.0.0-beta.1，应用程序正在运行，但是当我单击 subjects.component.html 中的“下一步”按钮时，我期待获得“profileDetails.component.html”的内容。我创建了一个 plunkr，例如。这里:http://plnkr.co/edit/jR3jnC6CzmRVCoVFrn1W?p=preview它在 plunkr 上不起作用，但我猜是由于我正在使用的 Angular 2 Material 按钮等，但谁能告诉我哪里出错了？这是我的 main.ts:

import {bootstrap} from '@angular/platform-browser-dynamic';
import {enableProdMode} from '@angular/core';
import {AppComponent} from './app/app.component';
import {HTTP_PROVIDERS} from '@angular/http';
import { appRouterProviders } from './app/app.routes';

//import {disableDeprecatedForms, provideForms} from '@angular/forms';

bootstrap(AppComponent, [
  // disableDeprecatedForms(),
  // provideForms(),
  HTTP_PROVIDERS,
  appRouterProviders
]);

这是 app.routes.ts:

import { provideRouter, RouterConfig } from '@angular/router';
import {SubjectsComponent} from './subjects.component';
import {ProfileDetailsComponent} from './profileDetails.component';
import {AgreementComponent} from './agreement.component';

export const routes: RouterConfig = [
  { path: 'card', component: BasicCardComponent },
  { path: 'subjects', component: SubjectsComponent },
  { path: 'profile', component: ProfileDetailsComponent },
  { path: 'agreement', component: AgreementComponent }
];

export const appRouterProviders = [
  provideRouter(routes)
];

这是我的 app.component.ts:

@Component({
  selector: 'my-app',
  template: `
  <a [routerLink]="['/card']"></a>
  <router-outlet></router-outlet>
  ` ,
 // templateUrl: 'app/app.component.html',
  styleUrls: ['app/app.component.css'],
  directives: [BasicCardComponent, MdButton,MdCard,MdToolbar,MdIcon,MdInput,MD_INPUT_DIRECTIVES,MdCheckbox,ROUTER_DIRECTIVES],
  providers:[MdIconRegistry]
})

流程有点像这样>profileDetails.component.html

在您的 app.component 中，您缺少路由器导出指令。

@Component({
  selector: 'my-app',

                          // you can do somthing like this
  template: `<card></card> 
            <router-outlet></router-outlet> `,
  styles: ....
  directives: [ROUTER_DIRECTIVES]
})
export class AppComponent {

}
