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 (8.1.27) does not satisfy that requirement. Problem 2 - Root composer.json requires symfony/console ^7.0 -> satisfiable by symfony/console[v7.0.0-BETA1, ..., 7.1.x-dev]. - symfony/console[v7.0.0-BETA1, ..., 7.1.x-dev] require php >=8.2 -> your php version (8.1.27) does not satisfy that requirement. Problem 3 - Root composer.json requires symfony/process ^7.0 -> satisfiable by symfony/process[v7.0.0-BETA1, ..., 7.1.x-dev]. - symfony/process[v7.0.0-BETA1, ..., 7.1.x-dev] require php >=8.2 -> your php version (8.1.27) does not satisfy that requirement. Problem 4 - illuminate/filesystem dev-master requires php ^8.2 -> your php version (8.1.27) does not satisfy that requirement. - illuminate/filesystem 11.x-dev is an alias of illuminate/filesystem dev-master and thus requires it to be installed too. - Root composer.json requires illuminate/filesystem ^11.0 -> satisfiable by illuminate/filesystem[11.x-dev (alias of dev-master)].
