Answer 1

execute the command:

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

he will install npm on your stray box.

Answer 2

A debian way would be to add a repo and install using apt-get

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

This will install the nodejs and npm debian method
