Victor Hugo Boiler Plate Dev Dependies [SOLVED]

I am ussing the Victor Hugo boiler plate (https://github.com/netlify/victor-hugo) on windows. I ran npm install & get this error:

ERROR in ./src/js/app.js
Module build failed: Error: Cannot find module 'babel-core’

I see in the package.json that babel-core is not listed as a dependency. I installed babel-core, and it fixed the errors. Was this intentional, if so what would be the reason?

This is the Netlify base theme. You should ask them in the theme’s repo.

That dependency is non Hugo related. Hugo is a single binary with no dependencies.
