Windows Installer The installer will download composer for you and set up your PATH environment variable so you can simply call composer from any directory. Download and run Composer-Setup.exe - it will install the latest composer version whenever it is executed. Command-line installation Run this in your terminal to get the latest Composer version: 
php -r "readfile('https://getcomposer.org/installer');" > composer-setup.php
php -r "if (hash('SHA384', file_get_contents('composer-setup.php')) === 'fd26ce67e3b237fffd5e5544b45b0d92c41a4afe3e3f778e942e43ce6be197b9cdc7c251dcde6e2a52297ea269370680') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); }"
