Your requirements could not be resolved to an installable set of packages. Problem 1 - laravel/framework 11.x-dev is an alias of laravel/framework dev-master and thus requires it to be installed too. - illuminate/console 11.x-dev is an alias of illuminate/console dev-master and thus requires it to be installed too. - laravel/framework dev-master requires php ^8.2 -> your php version (8.1.27) does not satisfy that requirement. - illuminate/console dev-master requires php ^8.2 -> your php version (8.1.27) does not satisfy that requirement. - Root composer.json requires illuminate/console ^11 -> satisfiable by illuminate/console[11.x-dev (alias of dev-master)], laravel/framework[11.x-dev (alias of dev-master)].
