Before the installation, ensure that we have installed Node.js 4.0+ on our machine. If not installed, then download the latest version of Node.js 8 "LTS" from https://nodejs.org Once we're done with the installation, we can download the Firebase CLI from npm (node package manager).

Run this command to install Firebase CLI globally on your system:

npm install -g firebase-tools

To verify the installation, run the following command; it prints the Firebase CLI version if it's installed properly on your system:

firebase --version
