Need help with building vendor/autoprefixer.js for ruby-autoprefixer-rais

[Pirate Praveen <praveen@onenetbeyond.org>]

Hi,

This was working fine before, I think its breaking now with nodejs 10 
(guess because of reference to buffer in the error and remembering some 
discussions around it).

Can someone help with this error? I tried adding node-buffer as build 
dependency, but that did not change anything.

Full error message,
