Modules - what am I doing wrong

Hi There

I am afraid I am complete newbee of Espruino, so please forgive me if this is some thing silly. I am hoping to use module but not have much luck

I am on Mac OsX and using the web IDE, I can see the projects so I think i am using the correct program.

on my root folder I've set up a project folder called 'Espruino' and have gone into the setting -> project and set the sandbox as ~/Espruino this created lots of folders including modules, I copied my module in there

now when i run my first line of code ie

const PoweredUP = require("node-poweredup");

it say the module can not be found am I doing something daft ?

Any Help would greatly appreciated

Cheers

James
