我知道我没有在我的App.module.ts中导入我的App-routing.module

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { HttpClientModule } from '@angular/common/http';
import { AppComponent } from './app.component';
import { PostListComponent } from './post/post-list.component';
import { PostService} from './post/post.service';
import { HomepageComponent } from './homepage/homepage.component';

@NgModule({
  declarations: [
    AppComponent,
    PostListComponent,
    HomepageComponent
  ],
  imports:[
    BrowserModule,
    HttpClientModule,
    **AppRoutingModule**
  ],
  providers: [
    PostService
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }
