Error: Couldn't find preset "es2015" relative to directory — Intellij Filewatcher

Question

trying to set up a Filewatcher with Intellij in order to use ES6 with Babel transpiler. I have followed their guide here, which seemed to install fine except for when I try to write javascript code and it executes the transpiler code, I get this error:

Error: Couldn't find preset "es2015" relative to directory "/Volumes/ShanStore/Main/Projects/NewWebsite"

I have Node v6.4.0 and npm 3.10.3 installed. I have a file named .babelrc in my root directory like so—

NewWebsite
  |_ .babelrc
  |_ index.html
  |_ script.js

and I ran these commands to install babel related things:

sudo npm install --save-dev babel-cli
sudo npm install --save-dev babel-preset-es2015

My .babelrc file looks like this:

{
  "presets": ["es2015"]
}

I've searched through the various solutions on here and none of them have worked. I have no idea what's wrong here! Any help?
