Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires illuminate/contracts ^10.0 -> satisfiable by illuminate/contracts[v10.0.0, ..., 10.x-dev]. - pestphp/pest-plugin-laravel[v1.4.0, ..., 1.x-dev] require laravel/framework ^7.30.6 || ^8.83.27 || ^9.47.0 || ^10.0.0 -> satisfiable by laravel/framework[v9.47.0, ..., 9.x-dev]. - Only one of these can be installed: laravel/framework[v9.0.0-beta.1, ..., 9.x-dev], illuminate/contracts[v10.0.0, ..., 10.x-dev]. laravel/framework replaces illuminate/contracts and thus cannot coexist with it. - Root composer.json requires pestphp/pest-plugin-laravel ^1.4 -> satisfiable by pestphp/pest-plugin-laravel[v1.4.0, 1.x-dev].
