我正在开发一个角度管理面板项目。管理员登录部分已完成，在仪表板中，我有一个侧面导航菜单，单击菜单项时，需要在主体 div 中加载相应的组件。我的主要出口插座是app.component.html这样放置的：

<router-outlet></router-outlet>

这工作得很好。以下是我的app-routing.module.ts

import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './components/home/home.component';
import { LoginPageComponent } from './components/login-page/login-page.component';
import { AuthGuard } from './guards/auth.guard';
import { ManageNewsComponent } from './components/manage-news/manage-news.component';
import { ManageUsersComponent } from './components/manage-users/manage-users.component';

const appRoutes: Routes = [
  // App Routes
  {
    path: '', component: HomeComponent, canActivate: [AuthGuard], children: [
      // Menu Routes
      { path: 'managenews', component: ManageNewsComponent, outlet: 'menu' },
      { path: 'manage_users', component: ManageUsersComponent, outlet: 'menu' }
    ]
  },
  { path: 'login', component: LoginPageComponent },

  // otherwise redirect to home
  { path: '**', redirectTo: '' }
];

export const routing = RouterModule.forRoot(appRoutes)

在app.module.ts

@NgModule({
  declarations: [
    ...
  ],
  imports: [
    ...
    routing,
    ...
  ],
  providers: [
    ...
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

在仪表板组件 html 中，我正在尝试执行此操作

<mat-toolbar color="warn">
    <mat-toolbar-row>
        <button type="button" aria-label="Toggle sidenav" mat-icon-button (click)="drawer.toggle()" color="primary">
            <mat-icon aria-label="Side nav toggle icon"><i class="fa fa-bars" style="font-size:24px;color:white"></i></mat-icon>
        </button>
    </mat-toolbar-row>
</mat-toolbar>
<mat-sidenav-container class="example-container">
    <mat-sidenav #drawer mode="side" opened role="navigation">
        <mat-nav-list>
            <a mat-list-item [routerLink]="[{ outlets: { primary: [''], menu: ['managenews'] } }]"> Manage News </a>
        </mat-nav-list>
    </mat-sidenav>
    <mat-sidenav-content>
        <router-outlet name="menu"></router-outlet>
    </mat-sidenav-content>
</mat-sidenav-container>

但是，单击“管理新闻”菜单项，页面未重定向，并且我在控制台中收到以下错误：

我被卡住了，通过教程无法弄清楚我在这里做错了什么。请帮忙。
