JSPM _angular_core.OptionalMetadata不是构造函数

Question

我试图将我的angular2（RC5）应用程序与JSPM捆绑在一起。捆绑似乎没问题。但是当我尝试运行我的应用程序时，我得到了JS JS错误

＆＃34;错误：（SystemJS）_angular_core.OptionalMetadata不是构造函数＆＃34;

我的config.js看起来像这样：

/**
 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    defaultJSExtensions: true,
    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/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',
      'ng2-translate': 'npm:ng2-translate',
      'ng2-bs3-modal': 'npm:ng2-bs3-modal',
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: './main.js',
        defaultExtension: 'js'
      },
      'angular2-in-memory-web-api': {
        main: './index.js',
        defaultExtension: 'js'
      }
    }
  });
})(this);

我的package.json看起来像这样

}

我用我的捆绑 ＆＃34; jspm捆绑app / main my_bundle.js＆＃34;

有人知道如何解决这个问题吗？
