When you have npm installed by a package manager, the only case you need to use sudo is a global installation of a gem.

Apologies, I mispoke. My point stands though- letting any rando who publishes to npm run scripts as a superuser on your machine is a bad idea.

nvm alias default 0.10 will set the default version for new terminals.

Good call!! Missed that in the docs.
