javascript - Angular 2 (CLI) 路由不起作用(无法读取未定义的属性 'split')

Question

为什么路由仅适用于 AppComponent 之后的第一个导入组件(下面的示例代码:路由仅适用于“PageNonFound”)？另外，我注意到在我的项目中添加路由后出现错误

错误

Error in ./AppComponent class AppComponent - 
inline template:13:42 caused by: 
Cannot read property 'split' of undefined

应用程序模块.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule, Routes } from '@angular/router';

import { AppComponent } from './app.component';
import { PageNotFoundComponent } from './page-not-found/page-not-found.component';
import { HomeComponent } from './home/home.component';

const appRoutes: Routes = [
  { path: '', redirectTo: '/home', pathMatch: 'full' },
  { path: '**', component: PageNotFoundComponent },
  { path: 'home', component: HomeComponent }
];

@NgModule({
  declarations: [
    AppComponent,
    PageNotFoundComponent,
    HomeComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    RouterModule.forRoot(appRoutes)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

应用程序组件.ts

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'testing';
}

App.component.html

<nav class="nav navbar navbar-custom navbar-fixed-top" role="navigation">
  <div class="container-fluid">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navbar">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" [routerLink]="['/home']">Test</a>
    </div>
    <div>
      <div class="collapse navbar-collapse" id="navbar">
        <ul class="nav navbar-nav">
          <li><a [routerLink]="['/home']" [routerLinkActive]="active">Home</a></li>
        </ul>
      </div>
    </div>
  </div>
</nav>
<router-outlet></router-outlet>

使用routerLinkActive="active"

或

[routerLinkActive]="['active']"

改变路线顺序

const appRoutes: Routes = [
  { path: 'home', component: HomeComponent },
  { path: '', redirectTo: 'home', pathMatch: 'full' },
  { path: '**', component: PageNotFoundComponent }, 
];
