How to integrate Reactstrap into mern-starter

I would like to use `reactstrap` with this mern-starter. But I find that I cannot start the project with `npm start` properly after I add an import statment in `client/modules/App/App.js`
e.g
`import 'bootstrap/dist/css/bootstrap.css';`

Start in client/modules/App/App.js and reproduce the reported failure with npm start after adding the Bootstrap stylesheet import. Check the startup output to identify the cause; done means the project starts successfully with the import present.
