我有如下配置的路由，当我在它加载的主要组件中添加LandingModuleComponent时，但如果我包含不同的模块则不行 .

const routes: Routes = [
    { path: '', redirectTo: '/landing', pathMatch: 'full' },
    { path: 'landing', component: LandingModuleComponent },
    { path: 'items', component: ItemsComponent },
    { path: 'item/:id', component: ItemDetailComponent }
];

我的LandingModuleComponent和LandingModule看起来像

@NgModule({
        imports: [CommonModule],
        declarations: [LandingModuleComponent],
        exports: [LandingModuleComponent]
    })

export class LandingModuleModule {}

@Component({
    selector: 'app-landing-module',
    moduleId: module.id,
    templateUrl: './landing-module.component.html',
    styleUrls: ['landing-module.component.css']
})
export class LandingModuleComponent implements OnInit {}

和主appModule看起来像

@NgModule({
    bootstrap: [AppComponent],
     imports: [NativeScriptModule, AppRoutingModule, LandingModuleModule]
    declarations: [AppComponent, ItemsComponent, ItemDetailComponent],
    providers: [ItemService],
    schemas: [NO_ERRORS_SCHEMA]
})

export class AppModule {}
