Using a Node Version Manager

There are a lot of different versions of Node out there. These tools will help you keep track of what version you are using, and also make it easy to install new versions and switch between them. They also make npm easier to set up :)

Installing Node.js and npm

Using nvm

nvm install 4
nvm use 4

Using nodist

nodist + 4
nodist use 4

You can test that it worked by typing:

node -v
