includePaths not working in latest node 6 and elixir

I have the following gulp file:

const elixir = require('laravel-elixir');
const neat = require('bourbon-neat').includePaths;

elixir(mix => {

    mix
        .sass('app.scss', null, {includePaths: neat});
});

I wanted to use bourbon-neat, but it gives me the following error, when using gulp

path.js:7
    throw new TypeError('Path must be a string. Received ' + inspect(path));

I don't know what am I doing wrong? I have searched Google, but couldn't find a solution. Some say downgrading to node 4 worked. But that isn't a solution.
