Question

我正在浏览here上的NG2教程，但我遇到了绊脚石。

当我尝试在我的AppRoutingModule文件中导入app.module.ts时，我得到了一个＆＃39; Cannot find module './app-routing.module＆＃39;错误。我在here以及其他解决方案中看过这篇文章，但它们似乎都与systemjs和不是 webpack有关。

这是我的 package.json ：

{
  "name": "heroes",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "start": "ng serve",
    "lint": "tslint \"src/**/*.ts\"",
    "test": "ng test",
    "pree2e": "webdriver-manager update",
    "e2e": "protractor"
  },
  "private": true,
  "dependencies": {
    "@angular/common": "2.0.0",
    "@angular/compiler": "2.0.0",
    "@angular/core": "2.0.0",
    "@angular/forms": "2.0.0",
    "@angular/http": "2.0.0",
    "@angular/platform-browser": "2.0.0",
    "@angular/platform-browser-dynamic": "2.0.0",
    "@angular/router": "3.0.0",
    "angular2-in-memory-web-api": "0.0.21",
    "core-js": "^2.4.1",
    "rxjs": "5.0.0-beta.12",
    "ts-helpers": "^1.1.1",
    "zone.js": "^0.6.23"
  },
  "devDependencies": {
    "@types/jasmine": "^2.2.30",
    "angular-cli": "1.0.0-beta.15",
    "codelyzer": "~0.0.26",
    "jasmine-core": "2.4.1",
    "jasmine-spec-reporter": "2.5.0",
    "karma": "1.2.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-cli": "^1.0.1",
    "karma-jasmine": "^1.0.2",
    "karma-remap-istanbul": "^0.2.1",
    "protractor": "4.0.5",
    "ts-node": "1.2.1",
    "tslint": "3.13.0",
    "typescript": "2.0.2"
  }
}

这是我的 app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule }   from '@angular/router';

// Imports for loading & configuring the in-memory web api
import { InMemoryWebApiModule } from 'angular2-in-memory-web-api';
import { AppRoutingModule } from './app-routing.module'; //ERROR
...


@NgModule({
  declarations: [
    AppComponent,
    HeroDetailComponent,
    HeroesComponent,
    DashboardComponent,
  ],
   imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    AppRoutingModule,
    InMemoryWebApiModule.forRoot(InMemoryDataService), //ERROR: Cannot find name 'InMemoryDataServiceInMemoryDataService

    RouterModule.forRoot([
      {
        path: '', redirectTo: '/dashboard', pathMatch: 'full'
      },
      {
        path: 'dashboard', component: DashboardComponent
      },
      {
        path: 'detail/:id', component: HeroDetailComponent
      },
      {
        path: 'heroes', component: HeroesComponent
      }
    ])
  ],
  providers: [HeroService],
  bootstrap: [AppComponent]
})
export class AppModule { }

这是我的规格（我正在使用角度CLI）：

angular-cli: 1.0.0-beta.15
node: 4.2.6
os: linux x64 (ubuntu)

不确定我还能尝试什么？我想我需要以某种方式导入模块？

我确实尝试并运行：

npm install angular-route

但这导致了：

├──UNMET PEER DEPENDENCY
@angular/common@2.0.0

├──UNMET PEER DEPENDENCY
@angular/core@2.0.0

├──UNMET PEER DEPENDENCY
@angular/platform-browser@2.0.0

└── angular-route@1.5.8

有人有任何建议吗？

查看包含所有文件的live示例

import { NgModule }             from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

import { DashboardComponent }   from './dashboard.component';
import { HeroesComponent }      from './heroes.component';
import { HeroDetailComponent }  from './hero-detail.component';

const routes: Routes = [
  { path: '', redirectTo: '/dashboard', pathMatch: 'full' },
  { path: 'dashboard',  component: DashboardComponent },
  { path: 'detail/:id', component: HeroDetailComponent },
  { path: 'heroes',     component: HeroesComponent }
];

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

根据评论，您似乎可能完全错过了app-routing文件。也许你错过了描述它的文章，或者有时候文档可能已经过时了。请查看plunker，其中显示了包含所需文件的实时工作示例。
