角2巡迴賽英雄，第7步錯誤

Question

我通過論壇看了看，但找不到任何相關信息。

我剛開始教程3天前，拿到第7步，當我加入InMemoryWebApiModule進來（如步驟詳細說明），我得到這個錯誤：

所有我的配置文件直接來自教程中提供的內容，但無論如何我都會在這裏提供它們。

任何想法，這是怎麼回事？

這裏是我的package.json：

{ 
    "name": "angular-quickstart", 
    "version": "1.0.0", 
    "scripts": { 
    "start": "tsc && concurrently \"tsc -w\" \"lite-server\" ", 
    "lite": "lite-server", 
    "tsc": "tsc", 
    "tsc:w": "tsc -w" 
    }, 
    "licenses": [ 
    { 
     "type": "MIT", 
     "url": "https://github.com/angular/angular.io/blob/master/LICENSE" 
    } 
    ], 
    "dependencies": { 
    "@angular/common": "~2.1.1", 
    "@angular/compiler": "~2.1.1", 
    "@angular/core": "~2.1.1", 
    "@angular/forms": "~2.1.1", 
    "@angular/http": "~2.1.1", 
    "@angular/platform-browser": "~2.1.1", 
    "@angular/platform-browser-dynamic": "~2.1.1", 
    "@angular/router": "~3.1.1", 
    "@angular/upgrade": "~2.1.1", 
    "angular-in-memory-web-api": "~0.1.13", 
    "bootstrap": "^3.3.7", 
    "core-js": "^2.4.1", 
    "reflect-metadata": "^0.1.8", 
    "rxjs": "5.0.0-beta.12", 
    "systemjs": "0.19.39", 
    "zone.js": "^0.6.25" 
    }, 
    "devDependencies": { 
    "@types/core-js": "^0.9.34", 
    "@types/node": "^6.0.45", 
    "concurrently": "^3.0.0", 
    "lite-server": "^2.2.2", 
    "typescript": "^2.0.3" 
    } 
} 

這裏是app.module.ts：

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

// Imports for loading & configuring the in-memory web api 
import { InMemoryWebApiModule } from 'angular-in-memory-web-api'; 
import { InMemoryDataService } from './in-memory-data.service'; 

import { AppRoutingModule } from './app-routing.module' 
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'; 

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

這裏是systemjs.config.js：

/** 
* System configuration for Angular samples 
* Adjust as necessary for your application needs. 
*/ 
(function (global) { 
    System.config({ 
    paths: { 
     // paths serve as alias 
     'npm:': 'node_modules/' 
    }, 
    // map tells the System loader where to look for things 
    map: { 
     // our app is within the app folder 
     app: 'app', 
     // angular bundles 
     '@angular/core': 'npm:@angular/core/bundles/core.umd.js', 
     '@angular/common': 'npm:@angular/common/bundles/common.umd.js', 
     '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js', 
     '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js', 
     '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js', 
     '@angular/http': 'npm:@angular/http/bundles/http.umd.js', 
     '@angular/router': 'npm:@angular/router/bundles/router.umd.js', 
     '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js', 
     // other libraries 
     'rxjs':      'npm:rxjs', 
     'angular-in-memory-web-api': 'npm:angular-in-memory-web-api', 
    }, 
    // packages tells the System loader how to load when no filename and/or no extension 
    packages: { 
     app: { 
     main: './main.js', 
     defaultExtension: 'js' 
     }, 
     rxjs: { 
     defaultExtension: 'js' 
     }, 
     'angular-in-memory-web-api': { 
     main: './index.js', 
     defaultExtension: 'js' 
     } 
    } 
    }); 
})(this);

乘坐看看CHANGELOG。您需要使用umd包，並從packages刪除它

In systemjs.config.js you should change the mapping to:

'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js' 

then delete from packages :

'angular-in-memory-web-api': {   
    main: './index.js',  
    defaultExtension: 'js'  
}
