Mac OS X

You can use the NodeJS installer from the Node website. However, installing Node using nvm has a lot of benefits including various security benefits.

Install nvm

You need to have Xcode or the Command Line Tools installed to provide a C++ compiler. Then, grab and run the install script:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.4/install.sh | bash

(This downloads the install.sh file and then pipes it to bash to be executed.)

Use it to install node

Now you can take advantage of the power of nvm to rock multiple versions of Node and hop around between them:

nvm install v6
nvm install 0.12
nvm use v6
node --version # prints 6.3.0
nvm use 0.12
node --version # prints 0.12.15
nvm ls # prints all the versions you have installed.

Windows

Use the installer on the NodeJS Site since nvm is not officially maintained for windows.
