带有AngularFire的localhost:3000/traceur SystemJS

问题描述

我选择了入门Angular2教程格式，并且仅在angularfire2部分.

I picked the getting started with Angular2 tutorial format and only added in the angularfire2 part.

我使用 angularfire2文档页面

下面是我的systemjs.config.js

Below is my systemjs.config.js

/**
 * 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',
      'angularfire2':               'npm:angularfire2'
    },
    // 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'
      },
      angularfire2: {
        main: 'index.js',
        defautExtension: 'js'
      }
    }
  });
})(this);

然后我只是像这样导入它:

Then I am simply importing it like so:

import { AngularFireModule } from 'angularfire2';

然后我不断收到此错误:

Then I keep getting this error:

有任何提示吗?

推荐答案

您的配置将angularfire2映射到node_modules/angularfire2/index.js，其编写为es6，因此SystemJS尝试使用traceur对其进行编译，但找不到它.

Your config maps angularfire2 to node_modules/angularfire2/index.js, which is written is es6, so SystemJS tries to compile it using traceur, and can not find it.

最简单的解决方法是对其进行配置，以便将捆绑软件加载到angular2/bundles/angularFire2.umd.js中，而不是在index.js中.

The easy fix would be to configure it so it loads the bundle in angular2/bundles/angularFire2.umd.js, not index.js.

所以packages

  angularfire2: {
    main: 'index.js'

需要更改为

  angularfire2: {
    main: 'bundles/angularFire2.umd.js'

而且，angularFire取决于Firebase，因此，正如@Jonathon Oates在他的回答中所说，您还需要提供Firebase的配置.

Also, angularFire depends on Firebase, so, as @Jonathon Oates said in his answer, you need to provide configuration for Firebase too.
