Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpunit/phpunit 5.7.* -> satisfiable by phpunit/phpunit[5.7.0, ..., 5.7.27]. - phpunit/phpunit[5.7.0, ..., 5.7.27] require php ^5.6 || ^7.0 -> your php version (8.3.12) does not satisfy that requirement.

Process completed with exit code 2.
