Bourbon importing failing in Jekyll set up

I'm currently using this Jekyll, gulp, sass

I'm attempting to add bourbon and neat to the project. by simply npm install node-neat and node bourbon.

For some reason when I run Gulp I run into the following error

Error: _scss/main.scss
Error: File to import not found or unreadable: bourbon

Why is it failing to import bourbon and neat?

here is the folder structure:

gulpfile.js

var bourbon     = require("node-bourbon").includePaths;
var neat        = require("node-neat").includePaths; 

This is killing me :( some help would be appreciated! Thanks
