The related lint-eslint plugin issue is at . This led me to update Atom to version 1.42, which fixed the problem.

I think that I know how to solve the issue, at least with WebStorm it works. It looks like Webstorm grabs on startup default Node/NPM version. If you manage multiple Node/NPM versions by nvm and the default one is v8.9.1 like in my scenario it won’t work.

To fix it you need to go to: Webstorm -> Preferences -> Languages and Frameworks -> Node.js and NPM and select correct Node interpreters, see screenshot below:
