Why is this failing? I reinstalled node and git.

It now is stuck on Unhandled rejection Error: Command failed: /usr/local/bin/git clone --depth=1 -q -b master https://github.com/debris/bignumber.js.git /Users/quantum/.npm/_cacache/tmp/git-clone-f59a30ef /Users/quantum/.npm/_cacache/tmp/git-clone-f59a30ef/.git: Permission denied

Sounds like your npm cache is messed up.

Try npm cache clean --force and reinstalling dependencies.
