Your requirements could not be resolved to an installable set of packages. Problem 1 - laravel/jetstream 5.x-dev is an alias of laravel/jetstream dev-master and thus requires it to be installed too. - laravel/jetstream[v4.2.0, ..., 4.x-dev] require illuminate/support ^10.17 -> satisfiable by laravel/framework[v10.17.0, ..., 10.x-dev], illuminate/support[v10.17.0, ..., 10.x-dev]. - laravel/jetstream dev-master requires php ^8.2.0 -> your php version (8.1.27) does not satisfy that requirement. - illuminate/support[v10.17.0, ..., 10.x-dev] require nesbot/carbon ^2.67 -> found nesbot/carbon[dev-master, 2.67.0, ..., 2.x-dev (alias of dev-master)] but it conflicts with your root composer.json require (2.63). - laravel/framework[v10.17.0, ..., 10.x-dev] require nesbot/carbon ^2.67 -> found nesbot/carbon[dev-master, 2.67.0, ..., 2.x-dev (alias of dev-master)] but it conflicts with your root composer.json require (2.63). - Root composer.json requires laravel/jetstream ^4.2|^5.0 -> satisfiable by laravel/jetstream[v4.2.0, v4.2.1, v4.2.2, 4.x-dev, 5.x-dev (alias of dev-master)].
