Bootstrap vs Angular 2:多脚本加载器中的错误!找不到模块:错误:/〜/ bootstrap/did/js/bootstrap.js

Question

我用ng new klw创建了一个新的Angular 2项目

1. 我安装了bootstrap: npm install bootstrap@next

2. 将样式和脚本添加到角度

   "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bootstrap 4到 angular-cli: npm install --save @ng-bootstrap/ngbootstrap

4. 将NgbModule导入添加到app.module.ts中
5. 添加到导入部分NgbModule到app.module.ts
6. 修改了app.module.html添加:<NgbAlert> Alert text </NgbAlert>

这是我错过的？

当我运行服务时,我得到以下错误:

我遇到过同样的问题。但我已经解决了。主要错误出现在来自“node_modules”文件夹的脚本和 CSS 中。转到“.angular-cli.json”文件并删除所有“node_modules”文件，然后手动输入所有脚本和 CSS 的路径..

谢谢
