Install Composer globally on Mac OS

  1. Code
Install Composer globally on Mac OS

# 1. Download Composer

Install download the composer using the following curl command in your terminal, this is provided by the project itself:

curl -sS https://getcomposer.org/installer | php

After running that command, there will be a file composer.phar in the current directory. You could use that command like this:

php composer.phar install

# 2. Installing Globally

In order to make composer available globally, allowing you to type composer install anywhere, you have to move the recently downloaded composer.phar to local userโ€™s bin folder:

mv composer.phar /usr/local/bin/composer

# 3. Open your shell profile

What shell are you using?

# Using bash? (Default shell on Mac OS <10.14, 2002-2019)

Open your ~/.bash_profile (in text edit ๐Ÿ˜)

open -e  ~/.bash_profile

# Using zsh? (Default shell on Mac OS 10.15+, 2019-Present)

Open your ~/.zshrc (in text edit ๐Ÿ˜)

open -e  ~/.zshrc

# 4. Add alias to composer

Add an alias to point at the composer.phar you moved into /usr/local/bin/*.

In your .zshrc or .bash_profile add the following line. It will create an alias of composer that can be used globally.

alias composer="php /usr/local/bin/composer"

# 5. Use composer globally

After restarting your terminal you will be able to access composer like below:

composer install 

There is a few way to accomplish this but I personally find the alias method the clearest and allows me to fully configure my shell. You could add /usr/local/bin to your PATH, see here.
