javascript - 无法在我的 angular-2 快速启动应用程序中加载 ng2-fullpage

Question

我正在尝试使用整页 + angular2:

我无法加载要使用的 ng2-fullpage 包，以下是我的文件:

systemjs.config.js

(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',
      // '@jquery':'npm:jquery/jquery.min.js',

      // other libraries
      'rxjs':                      'npm:rxjs',
      'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js',
      'ng2-fullpage':               'npm:ng2-fullpage',
      'jquery':                     'npm:jquery/dist/jquery.js',
      'fullpage.js':                'npm:fullpage.js/jquery.fullPage.js'
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        defaultExtension: 'js'
      },
      rxjs: {
        defaultExtension: 'js'
      }
    }
  });
})(this);

app.module.ts

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {HttpModule} from '@angular/http';
import {routing} from './app.routing';
import {NavbarComponent} from './components/navbar/navbar.component';
import { MnFullpageDirective, MnFullpageService } from 'ng2-fullpage/ng2-fullpage';

import { AppComponent }  from './app.component';
import { ResumeComponent } from './components/resume/resume.component';
import { AboutComponent } from './components/about/about.component';
import {HomeComponent} from './components/home/home.component'



@NgModule({
  imports:      [ BrowserModule,HttpModule, routing ],
  declarations: [ AppComponent, ResumeComponent, AboutComponent, HomeComponent, NavbarComponent,MnFullpageDirective],
  bootstrap:    [ AppComponent ],
  providers: [MnFullpageService]
})
export class AppModule { }

对于 ng2-fullpage，我的 node_modules 文件夹结构如下所示:

我得到的错误是:

在我的网络选项卡中，当我点击 ng2-fullpage 时，我得到以下信息:

Cannot GET /node_modules/ng2-fullpage/ng2-fullpage

我一直在尝试使用 npm 页面上给出的 plunkr 解决这个问题，它似乎可以工作，但它对我不起作用。 plunkr 页面是

[ http://embed.plnkr.co/1p9zKp4CNI1HncAh1h9m][2]

控制台错误:

修改您的 systemjs.config.js。改变这个:

'ng2-fullpage':               'npm:ng2-fullpage',

为此:

'ng2-fullpage':               'npm:ng2-fullpage/bundles/ng2-fullpage.bundle.js',
