- phpunit/phpunit 5.5.4 requires php ^5.6 || ^7.0 -> your PHP version (7.0.26-2+ubuntu16.04.1+deb.sury.org+2) overridden by "config.platform.php" version (5.5) does not satisfy that requirement.Source : https://stackoverflow.com/questions/48100614/why-do-i-get-a-version-mismatch-during-composer-install-for-an-outdated-php-vers | Last Update : Sun, 10 Oct 21
