Installing node.js and npm on MAC

Node Js can be installed from brew Or we can download and install manually.

1. Installing node through brew:

First we need to install homebrew in MAC

  • Please execute the below command in terminal to install brew
    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  • Close the terminal and open it again
  • Run brew update to update brew to latest version

    brew update
  • Run brew doctor as a safe measure to make sure your system is ready to brew
    brew doctor
  • Now execute the below command in terminal to install nodeJs
    brew install node

2. Installing node manually:

  • Please download the latest version of Node Js from http://nodejs.org.
  • Node Js download page
  • Double click on the downloaded apk file.
  • Node Js installation wizard
  • Click on ‘Continue’ button under installation wizard and complete the installation.

After installing the NodeJs by following either of the above 2 procedures we need to verify whether npm is ready to use.

Now, open another terminal window and type ‘npm’ and hit enter.

If you observe ‘-bash: npm: Command not found’, you need to append npm location to the $PATH environment variable. Please execute the below commands in set $PATH for npm.

1. printf '%s\n' "export PATH=/usr/local/bin:\$PATH" >> ~/.bash_profile
2. printf '%s\n' "export PATH=/usr/local/bin:\$PATH" >> ~/.profile

Your NodeJs is installed and npm is ready to use.
