Question

我想重复

我添加了

import './rxjs-extensions';

到AppModule

现在看起来像这样：

import { NgModule }       from '@angular/core';
import { BrowserModule }  from '@angular/platform-browser';
import { FormsModule }    from '@angular/forms';
import { HttpModule }    from '@angular/http';
import './rxjs-extensions';

import { AppComponent }        from './app.component';
import { HeroDetailComponent } from './hero-detail.component';
import { HeroesComponent }     from './heroes.component';
import { HeroService }         from './hero.service';
import {DashBoardComponent} from "./dashboard.component";
import {AppRoutingModule} from "./app-routing.module";
import {InMemoryWebApiModule} from "angular-in-memory-web-api";
import {InMemoryDataService} from "./in-memory-data.service";
import {HeroSearchComponent} from "./hero-search.component";

@NgModule({
    imports: [
        BrowserModule,
        FormsModule,
        AppRoutingModule,
        HttpModule,
        InMemoryWebApiModule.forRoot(InMemoryDataService)
    ],
    declarations: [
        AppComponent,
        HeroDetailComponent,
        HeroesComponent,
        DashBoardComponent,
        HeroSearchComponent
    ],
    providers: [
        HeroService
    ],
    bootstrap: [AppComponent]
})
export class AppModule {
}

当我启动应用程序时，我在浏览器控制台中看到错误：

    Error loading http://localhost:3000/app/rxjs-extensions.js as "./rxjs-extensions" from http://localhost:3000/app/app.module.js

我错过了什么？

无法加载资源... rxjs-extensions.js
