将 jquery 添加到 angular 2 wepack 项目（Bootstrap 的 JavaScript 需要 jQuery）

Question

I'm using the angular-cli .net core starter. Now I'm adding my own css + javascript and getting following error:

An unhandled exception occurred while processing the request. Exception: Call to Node module failed with error: Prerendering failed because of error: Error: Bootstrap's JavaScript requires jQuery

I already tried:

npm install jquery 

+

import $ from 'jquery'; => in app component

How do you configure jquery with webpack / angular2 ?

Thanks!
