Remove Your older versions and install the latest version of Composer,

Remove Your older version: sudo rm -f /usr/local/bin/composer

Download the installer: sudo curl -s https://getcomposer.org/installer | php

Move the composer.phar file: sudo mv composer.phar /usr/local/bin/composer

Manually update the composer:

wget -cO - https://getcomposer.org/composer-stable.phar > /usr/local/bin/composer

Check the installed composer version:

composer --version
