import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpClientModule } from '@angular/common/http';
import { RouterModule } from '@angular/router';

@NgModule({
  declarations: [
    AppComponent,
    NavMenuComponent,
    HomeComponent,
    VehicleFormComponent
  ],
  imports: [
    BrowserModule.withServerTransition({
      appId: 'ng-cli-universal'
    }),
    FormsModule,
    HttpClientModule,
    FormsModule,
    ToastyModule.forRoot(),
    RouterModule.forRoot([
      {
        path: '',
        component: HomeComponent,
        pathMatch: 'full'
      },
      {
        path: 'vehicles/new',
        component: VehicleFormComponent
      }
    ])
  ],
  providers: [VehicleService],
  bootstrap: [AppComponent]
})
export class AppModule {}

这基本上是由于在构建 Angular 应用程序时发生了任何类型的编译错误。确保 npm 控制台是干净的。为此，只需从 VSCode npm 控制台运行命令 npm start。
