title: XHR error loading traceur.js while using react-select
body: <p>When I'm trying to start project with react-select I have XHR error loading traceur.js. I import library how it's written in official guide. When I'm trying use react-select in codesandbox it works correct. In my project even when I import <code>import Select from 'react-...'</code> IDEA's autocomplete doesn't see 'react-select'</p>
  <p>I don't understand why this error appears and why</p>
  <p>Did anyone have issue like this?</p>
