Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires psalm/plugin-phpunit ^0.16.0 -> satisfiable by psalm/plugin-phpunit[0.16.0, 0.16.1]. - psalm/plugin-phpunit[0.16.0, ..., 0.16.1] require vimeo/psalm dev-master || dev-4.x || ^4.5 -> found vimeo/psalm[4.5.0, ..., 4.30.0] but it conflicts with your root composer.json require (^5.0 ). Problem 2 - cakephp/cakephp[5.0.0, ..., 5.0.9] require php >=8.1 -> your php version (8.0.30) does not satisfy that requirement. - Root composer.json requires cakephp/cakephp ^5.0.0 -> satisfiable by cakephp/cakephp[5.0.0, ..., 5.0.9].
