I am using Webstorm 2017.3 and I cannot fix an issue with import form reselect:
Cannot resolve symbol 'createStructuredSelector' when doing:
import { createStructuredSelector } from 'reselect';
I found similar issues on the the web concerning other packages (react-native for instance) so I guess it is a package related issue.
Everything works perfectly but this warning in the IDE is a bit annoying.

You can use 'reselect/es'.
Ahh thanks 209. It can't find the createStructuredSelector function because there's no index.js file in the directory, hence "reselect/es"
