This is a guide written to describe how to set up and install npm and node.js onto your Mac laptop.
How to install npm and Node.js on a Mac OS laptop
1. Install Mac OS installer from Node.js
Visit NodeJS at nodejs.org/en/download/ and install this onto your Mac laptop.
You'll find that npm is installed with Node.js. As npm is distributed with Node.js- which means that when you download Node.js, you automatically get npm installed on your computer.
2. Downloading and installing Node.js and npm
Confirm that it is installed correctly by checking your version of npm and Node.js§.
To see if you already have Node.js and npm installed and check the installed version, run the following commands:
node -v<br>npm -v<br><br><strong>$ node -v</strong><br>v10.16.0<br><br><strong>$ npm -v</strong><br>6.9.2
4. Run this npm install npm@latest -g
npm is a separate project from Node.js. So even if you’ve just downloaded Node.js (which also includes npm), you’ll probably need to update your npm.
To update your npm, type this into your terminal:
<strong>$ sudo npm install npm@latest -g</strong><br>/usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js<br>/usr/local/bin/npx -> /usr/local/lib/node_modules/npm/bin/npx-cli.js<br>+ email@example.com<br>updated 1 package in 4.132s
