 public

This guide will walk you through installing Node.js and the Node Package Manager (NPM).

To complete this guide, you’ll need:

  • A mac computer
  • An internet connection

You may already have it!

Depending on how your machine was set up, you might already have Node.js installed.

  1. Open the Terminal application. It lives in the Applications > Utilities folder. You can also press Command + Space, type “Terminal”, and select Terminal under Applications.
  1. In the Terminal, type node -v and press Enter.
If you see a version number (as shown above) then congratulations! You already have Node.js installed. Skip to the last section, Update Node.js, to ensure that your version is up to date.

If not, or if you see a response such as  command not found: node then you do not have Node.js installed and you should continue with this article.
