错误：'AppRoutingModule‘模块无法导入自身

// 错误示例
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { AppRoutingModule } from './app-routing.module'; // 错误的导入语句

const routes: Routes = [
  // 路由配置
];

@NgModule({
  imports: [RouterModule.forRoot(routes), AppRoutingModule], // 错误的导入语句
  exports: [RouterModule]
})
export class AppRoutingModule { }

// 正确示例
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';

const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'about', component: AboutComponent }
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }
