Angular2 Material 映射问题

Question

我正在使用 Angular2 beta 和 angular2-material alpha.3，它们是兼容的，但我在映射方面遇到问题。

在我的 public/index.html 中我有这个系统设置

System.config (
            {
                packages: {
                    app: {
                        format          : 'register',
                        defaultExtension: 'js'
                    }
                },
                map: {
                    '@angular2-material/input': 'node_modules/@angular2-material/input'
                }
            }
        );
        System.import ( 'app/boot' ).then ( null, console.error.bind ( console ) );

但是在我的一个组件中，当我尝试导入并将其添加到要在模板中使用的指令时，如下所示:

import { Component } from 'angular2/core';
import { ControlGroup, Validators, FormBuilder } from 'angular2/common';
import { Http, Headers } from 'angular2/http';
import { ConfigService } from '../../services';
import {MD_INPUT_DIRECTIVES} from '@angular2-material/input';


@Component({
    selector: 'test-form',
    providers: [],
    templateUrl: ConfigService.APP_FOLDER + '/components/test/test.html',
    directives: [MD_INPUT_DIRECTIVES]
}) 

我收到此错误:

<script>
        System.config (
            {
                map: {
                    '@angular2-material' : 'libs/@angular2-material',
                },
                packages: {
                    app: {
                        format          : 'register',
                        defaultExtension: 'js'
                    },
                    '@angular2-material/core' : {
                        main: 'core.js',
                        defaultExtension: 'js'
                    },
                    '@angular2-material/input' : {
                        main: 'input.js',
                        defaultExtension: 'js'
                    }
                }
            }
        );
        System.import ( 'app/boot' ).then ( null, console.error.bind ( console ) );
    </script>

已修复，因为您需要映射 @angular2-material，然后需要将 angular2-material 中的每个包定义到其 JS 文件。
