Bootstrap vs Angular 2：多脚本加载器中的错误！未找到模块：错误：/~/bootstrap/dist/js/bootstrap.js

问：

我用 ng new klw 创建了一个新的 Angular 2 项目

1. 我安装了引导程序：npm install bootstrap@next

2. 在 Angular 中添加了样式和脚本

   "styles": [
       "styles.css",
   "../node_modules/bootstrap/dist/css/bootstrap.css"
     ],
     "scripts": [
   "../node_modules/jquery/dist/jquery.js",
   "../node_modules/tether/dist/js/tether.js",
   "../node_modules/bootstrap/dist/js/bootstrap.js"
     ],
   

3. 集成引导程序 4 到angular-cli: npm install --save @ng-bootstrap/ngbootstrap

4. 添加了 NgbModule 导入到app.module.ts
5. 已添加到将 NgbModule 部分导入app.module.ts
6. 修改后的 app.module，.html 添加：<NgbAlert> Alert text </NgbAlert>

这是我错过的吗？

当我运行ng serve时，我收到以下错误：
