Install Node.js and npm using Homebrew on OS X and macOS

 

Install Node.js and npm with Homebrew

First, install Homebrew.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then run brew update to make sure Homebrew is up to date.

brew update

run brew doctor to make sure your system is ready to brew. Run the command below and follow any recommendations from brew doctor.

brew doctor

Next, add Homebrew’s location to your $PATH in your .bash_profile or .zshrc file.

export PATH="/usr/local/bin:$PATH"

Next, install Node (npm will be installed with Node):

brew install node

To test out your Node and npm install, try installing Grunt (you might be asked to run with sudo):

npm install -g grunt-cli

Now you’ve installed Node.js, npm, and Grunt.
