</app-header>

<div class="mainwrap">
        <div class="heading"> 
        Registration
        </div>

        <mat-tab-group>
            <mat-tab label="Tab 1">Content 1</mat-tab>

应用程序模块.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { AppComponent } from './app.component';
import { HeaderComponent } from './header/header.component';
import { RegistrationComponent } from './registration/registration.component';
import {MatTabsModule} from '@angular/material';

@NgModule({
  declarations: [
    AppComponent,
    HeaderComponent,
    RegistrationComponent
  ],
  imports: [
    BrowserModule,
    MatTabsModule,
    RouterModule.forRoot(
    [
    {
      path: '',
      redirectTo: 'registration',
      pathMatch: 'full'
    },
    {
    path: 'registration',
    component: RegistrationComponent
    }
    ])
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

经过一番研究，我找到了答案

我没有在 app.module.ts 中导入 BrowserAniminationModule，因此我无法正确使用选项卡。
