带有ng2-bootstrap的Webpack Angular2：未定义系统

Question

我正在使用Webpack Angular2（See here），我想要包含ng2-bootstrap（See here）。

ng2-bootstrap依赖于SystemJS，但我不知道如何正确包含它。

这是我的package.json：

这是我的vendor.browser.ts：

// Angular 2
import '@angular/platform-browser';
import '@angular/platform-browser-dynamic';
import '@angular/core';
import '@angular/common';
import '@angular/forms';
import '@angular/http';
import '@angular/router';

// AngularClass
import '@angularclass/hmr';

// RxJS
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/mergeMap';

import 'jquery';
import 'bootstrap/dist/js/bootstrap';
import 'admin-lte/dist/js/app';
import 'ng2-bootstrap/bundles/ng2-bootstrap'

if ('production' === ENV) {
  // Production
} else {
 // Development
}

但是，我在运行时收到此错误：

当我在vendor.browser.ts中添加import 'systemjs/dist/system';时，出现编译错误：

ERROR in ./~/systemjs/dist/system.js                                                                                                 
Module not found: Error: Can't resolve 'fs' in 'c:\Projects\Fandango\front\node_modules\systemjs\dist'

@ ./src/vendor.browser.ts                                                                                                           
@ multi vendor

我是webpack的新手，但我认为我走在正确的轨道上？

有没有人有想法？

我认为您应该从vendor.browser.ts中删除“import'ng2-bootstrap / bundles / ng2-bootstrap”，因为webpack将在app.module.ts或main.ts中查看导入语句并导入需要的组件对于您的项目，并且在添加时不会导入整个ng2-bootstrap库 您在vendor.browser.ts文件中“导入'ng2-bootstrap / bundles / ng2-bootstrap'”。

Look here for using ng2-bootstrap with webpack:
