Now that Node.js has been installed, let's install Angular CLI (https://cli.angular.io). Open a Command Prompt / Terminal and run the following command:

$ npm install -g @angular/[email protected]

Once you have successfully installed, you can run the following command to verify the installation:

$ ng -v
