Answer 1

The debian way would be to add the repo and install with apt-get

curl --silent --location https://deb.nodesource.com/setup_0.12 | sudo bash -
sudo apt-get update
sudo apt-get install --yes nodejs

That will install nodejs and npm the debian way

Here you have a vagrant provision i build that comes with nodejs https://github.com/Sudakatux/vagrant-liferay-others

run command :

wget https://npmjs.org/install.sh 
sudo chmod +x install.sh
sudo ./install.sh

it will install npm to your vagrant box.
