Angular 2路由器错误:路由'undefined'的配置无效

Question

我使用的是Angular 2路由器3.0.0-beta.2.

似乎无法通过单一途径工作.

"错误:路由'undefined'的配置无效:组件,redirectTo,必须提供子项"

main.ts

import { bootstrap } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppComponent, environment, appRouterProviders } from './app';

bootstrap(AppComponent, [appRouterProviders])
  .catch(err => console.error(err));

app.routes.ts

import {provideRouter, RouterConfig}  from '@angular/router';
import {HomeComponent} from './';

export const appRoutes:RouterConfig = [
  [{
    path: '',
    redirectTo: '/home',
    pathMatch: 'full'
  },{
     path: 'home',
     component: HomeComponent
  }]
];

export const routes: RouterConfig = [
  ...appRoutes
];

export const appRouterProviders = [
  provideRouter(routes)
];

app.component.ts

import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES }  from '@angular/router';

 @Component({
  moduleId: module.id,
  selector: 'app-root',
  templateUrl: 'app.component.html',
  directives: [ROUTER_DIRECTIVES]
})
export class AppComponent {
  title = 'app works!';
}

home.component.ts

import { Component, OnInit } from '@angular/core';
import { ROUTER_DIRECTIVES }    from '@angular/router';

@Component({
  moduleId: module.id,
  selector: 'app-home',
  templateUrl: 'home.component.html',
  directives: [ROUTER_DIRECTIVES]
})
export class HomeComponent implements OnInit {

  constructor() { }

  ngOnInit() {
  }

}

app.component.html

<h1>
  App Shell
</h1>
<router-outlet></router-outlet>

您需要为HomeComponent导入提供正确的相对路径:

而不是这个:

import {HomeComponent} from './';

做这个:

import {HomeComponent} from './home.component';

app.routes.ts

import {provideRouter, RouterConfig}  from '@angular/router';
import {HomeComponent} from './home.component';  // you need to provide correct relative path

const appRoutes:RouterConfig = [                 //removed export
      {                                          // removed square bracket
        path: '',
        redirectTo: '/home',
        pathMatch: 'full'
      },{
         path: 'home',
         component: HomeComponent
      }
    ];


    export const appRouterProviders = [
      provideRouter(routes)
    ];

main.ts

import { bootstrap } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppComponent} from './app.component';     //please provide right path
import {appRouterProviders } from './app.routes';  // added 

bootstrap(AppComponent, [appRouterProviders])
  .catch(err => console.error(err));

对于未来的读者：

如果有问题的组件未在模块上注册，也会显示此错误，并且可能会造成混乱。
