在systemjs中映射sockjs-client

我使用的是typescript和angular2，我想在我的項目中使用SockJS。我運行：npm install sockjs-client。現在我想在systemjs.config.js中添加node_modules/sockjs-client的映射。它是如何文件現在看起來：在systemjs中映射sockjs-client

/** 
* System configuration for Angular 2 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', 
      'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api', 
      'sockjs-client': 'npm:sockjs-client', 
      'stompjs': 'npm:stompjs/lib/stomp.min.js' 
     }, 
     // 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' 
      }, 
      'angular2-in-memory-web-api': { 
       main: './index.js', 
       defaultExtension: 'js' 
      } 
     } 
    }); 
})(this);

而且我已經在瀏覽器中以下異常：

localhost/:16 Error: Error: XHR error (404 Not Found) loading http://localhost:8080/node_modules/sockjs-client(…)

什麼是sockjs客戶端庫正確systemjs映射？
