Uninstall nodejs from OSX Yosemite

	# first:
	lsbom -f -l -s -pf /var/db/receipts/org.nodejs.pkg.bom \| while read f; do sudo rm /usr/local/${f}; done
	sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*

	# To recap, the best way (I've found) to completely uninstall node + npm is to do the following:

	# go to /usr/local/lib and delete any node and node_modules
	cd /usr/local/lib
	sudo rm -rf node*
