Node Sass could not find a binding for your current environment: 
OS X 64-bit with Node.js 4.x
Found bindings for the following environments:
  - OS X 64-bit with Node.js 6.x
I get that. Sort of. Except:   node -v => v6.9.2
So what is it getting my current environment from? I'm using nvm to manage node versions.. but I'm getting conflicting information about what version of node I'm running.
I also followed these instructions to upgrade
How to I just use v6.9.2 everywhere?
