Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires php ^8.2 but your php version (8.1.2) does not satisfy that requirement. Problem 2 - Root composer.json requires orchestra/testbench 9.x-dev -> satisfiable by orchestra/testbench[9.x-dev]. - orchestra/testbench 9.x-dev requires php ^8.2 -> your php version (8.1.2) does not satisfy that requirement. Problem 3 - phpunit/phpunit[dev-main, 11.0.1, ..., 11.1.3] require php >=8.2 -> your php version (8.1.2) does not satisfy that requirement. - phpunit/phpunit 11.3.x-dev is an alias of phpunit/phpunit dev-main and thus requires it to be installed too. - Root composer.json requires phpunit/phpunit ^11.0.1 -> satisfiable by phpunit/phpunit[11.0.1, ..., 11.3.x-dev (alias of dev-main)].
