Require not working NodeJS Aframe

This is my first post. I tried to solve it on my own but apparenlty there is something that I don't understand.
I cannot make require work on my Webstorm Project.

In my webstorm project I'm using aframe and normal Javascript. But now I need to use flux. For this reason I need the require keyword to work. I also tried requirejs but it's not working either.

I dunno if this screen is usefull also I don't know if you need some other information. I can tell you that I've the last version of nodejs and I've flux installed with npm inside the project. 
Thx for help
