So I ran the following:
> meteor npm i npm -g ... > meteor npm -v 5.0.3
haha! Woot woot! It is so much faster!!!
Is this supported by MDG?
A cool thing about NPM v5 is that it reads
prepare fields from package.json for any packages that it installs from source control, so that those packages can do any sort of building and preparing when they are specifically installed from source control (for example from GitHub).
