Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires php >=8.1 but your php version (8.0.30) does not satisfy that requirement. Problem 2 - roadiz/models dev-develop requires php >=8.1 -> your php version (8.0.30) does not satisfy that requirement. - roadiz/models 2.2.x-dev is an alias of roadiz/models dev-develop and thus requires it to be installed too. - Root composer.json requires roadiz/models 2.2.x-dev -> satisfiable by roadiz/models[2.2.x-dev (alias of dev-develop)].
