Question

我尝试为Auth0（angular2-jwt）和Angular 2.0.0-beta.6配置SystemJS，但总是出现以下错误：

GET http://localhost:3000/angular2/http 404 (Not Found)fetchTextFromURL @ system.src.js:1068(anonymous function) @ system.src.js:1649lib$es6$promise$$internal$$initializePromise @ angular2-polyfills.js:515lib$es6$promise$promise$$Promise @ angular2-polyfills.js:806(anonymous function) @ system.src.js:1648(anonymous function) @ system.src.js:2669(anonymous function) @ system.src.js:3233(anonymous function) @ system.src.js:3500(anonymous function) @ system.src.js:4116(anonymous function) @ system.src.js:4324(anonymous function) @ system.src.js:4564(anonymous function) @ system.src.js:326Zone.run @ angular2-polyfills.js:1243zoneBoundFn @ angular2-polyfills.js:1220lib$es6$promise$$internal$$tryCatch @ angular2-polyfills.js:468lib$es6$promise$$internal$$invokeCallback @ angular2-polyfills.js:480lib$es6$promise$$internal$$publish @ angular2-polyfills.js:451(anonymous function) @ angular2-polyfills.js:123Zone.run @ angular2-polyfills.js:1243zoneBoundFn @ angular2-polyfills.js:1220lib$es6$promise$asap$$flush @ angular2-polyfills.js:262
angular2-polyfills.js:1243 Error: XHR error (404 Not Found) loading http://localhost:3000/angular2/http(…)

SystemJS：

<script>
    //configure system loader
    System.config({
      packages: {
        app: {
            format: 'register',
            defaultExtension: 'js'
        },
        'angular2-jwt': {
            defaultExtension: 'js'
        }
      },
      map: {
        'angular2-jwt': 'node_modules/angular2-jwt/angular2-jwt.js'
      }
    });
  </script>

此外，我已阅读SystemJS documentation，但我不确定如何解决此问题。

您似乎没有将angular2/http脚本导入其他脚本：

<script src="https://code.angularjs.org/2.0.0-beta.6/angular2.dev.js"></script>
<script src="https://code.angularjs.org/2.0.0-beta.6/http.js"></script> <!-- add this -->

别忘了引导它，否则你会得到：

例外：没有Http的提供商！（AppComponent - ＆gt; Http）
...
错误：DI例外......

引导它：

import {bootstrap}    from 'angular2/platform/browser'
import {HTTP_PROVIDERS} from 'angular2/http';
import {AppComponent} from './app.component'

bootstrap(AppComponent, [HTTP_PROVIDERS]);

如何使用Auth0配置SystemJS？
