angular2 最终版本。ng-bootstrap alpha v.5
引导组件适用于 html，但是当我尝试按以下方式导入它们时
import {ViewChild} from "@angular/core/src/metadata/di";
import {NgbDropdown} from "@ng-bootstrap/ng-bootstrap/dropdown/dropdown”;
我收到以下错误。
zone.js:136drainMicroTaskQueue @ zone.js:368ZoneTask.invoke @ zone.js:308
zone.js:1274 GET http://localhost:8080/abc/node_modules/@ng-bootstrap/ng-bootstrap/bundles/ng-bootstrap.js/dropdown/dropdown.js 404 (Not Found)
当然看起来它正在尝试从不存在的捆绑包中加载下拉列表。捆绑包只包含 ng-bootstrap.js 'dropdown' 是捆绑包之外的不同组件。我认为它与 systemjs.config.js 有一些关系，有人可以帮忙吗？
以下是我的 systemjs.config.js 文件
(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
