Question

mat-tab-group在Angular 5项目中不起作用，我已经按照他们的文档中的说明安装了所有必需的依赖项，我知道Angular 4已经存在与此类似的问题，即说要安装BrowserAnimationsModule，但是我尝试过仍然无法正常工作，

模板：

<div class="try">
  <mat-tab-group>
    <mat-tab label="First"> Content 1 </mat-tab>
    <mat-tab label="Second"> Content 2 </mat-tab>
    <mat-tab label="Third"> Content 3 </mat-tab>
  </mat-tab-group>
</div>

appModule.ts文件：

imports: [
BrowserModule,
NgxPaginationModule,
HttpModule,
TabModule,
FormsModule,
NgxPopper ,
MDBBootstrapModule.forRoot(),
RouterModule.forRoot(
  appRoutes,
  { enableTracing: true } // <-- debugging purposes only
),
BrowserAnimationsModule,
MatTabsModule,
MatTableModule,

HTML：

<mat-tab-group >
  <mat-tab label="Short tab">
    <div class="example-small-box mat-elevation-z4">
      Small content
    </div>
  </mat-tab>
  <mat-tab label="Long tab">
    <div class="example-large-box mat-elevation-z4">
      Large content
    </div>
  </mat-tab>
</mat-tab-group>

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { MatLabel } from '@angular/material';
import {MatTabsModule} from '@angular/material/tabs';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';



import { AppComponent } from './app.component';
import { HelloComponent } from './hello.component';

@NgModule({
  imports:      [ BrowserModule, FormsModule,BrowserAnimationsModule,MatTabsModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

style.css：

@import "~@angular/material/prebuilt-themes/indigo-pink.css";

Answer 2

您需要将其添加到组件所在的模块中

import { MatTabsModule } from '@angular/material';

@NgModule({
  imports: [
   ...
   MatTabsModule,
   ...
  ]
})

导出类SomeModule {}
