我正在尝试添加角度材料组件 . 但该组件无法正常工作 . 那个错误说

Uncaught Error: Template parse errors: 'mat-option' is not a known element:
// ...

我认为错误来自 app.module.ts ：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { SidebarComponent } from './sidebar/sidebar.component';
import { PostsComponent } from './posts/posts.component';
import { UsersComponent } from './users/users.component';
import { DetailsComponent } from './details/details.component';
import { HttpClientModule } from '@angular/common/http';
import { FooterComponent } from './footer/footer.component'; 
import {MatButtonModule, MatCheckboxModule} from '@angular/material';
import {MatFormFieldModule} from '@angular/material/form-field';
import { MyFormComponent } from './my-form/my-form.component';
@NgModule({
  declarations: [
    AppComponent,
    SidebarComponent,
    PostsComponent,
    UsersComponent,
    DetailsComponent,
    FooterComponent, MyFormComponent
  ],
  imports: [
    BrowserModule, AppRoutingModule,HttpClientModule,MatButtonModule, MatCheckboxModule,MatFormFieldModule
  ]
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }
angular typescript angular-material angular6

    您需要导入 MatSelectModule 因为 mat-option 在此模块中声明并将其添加到 AppModule 导入

    import { ..., MatSelectModule, ... } from '@angular/material';

@NgModule({
   imports: [ ..., MatSelectModule, ...]
})
export class AppModule { }

    你需要导入 MatSelectModule ，

    imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    MaterialModule,
    MatSelectModule,
    //..Other modules here
],

    您需要在AppModule.ts中导入 MatSelectModule

    import {MatButtonModule, MatCheckboxModule, MatSelectModule} from '@angular/material';

imports: [
    BrowserModule,
    AppRoutingModule,
    HttpClientModule,
    MatButtonModule,
    MatCheckboxModule,
    MatFormFieldModule,
    MatSelectModule
  ]
