Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires orchestra/testbench ^9.0 -> satisfiable by orchestra/testbench[9.x-dev]. - orchestra/testbench 9.x-dev requires laravel/framework 11.x-dev -> found laravel/framework[dev-master, 11.x-dev (alias of dev-master)] but it conflicts with your root composer.json require (^10.17). Problem 2 - Only one of these can be installed: laravel/framework[v10.17.0, ..., 10.x-dev], illuminate/console[dev-master]. laravel/framework replaces illuminate/console and thus cannot coexist with it. - illuminate/console 11.x-dev is an alias of illuminate/console dev-master and thus requires it to be installed too. - Root composer.json requires illuminate/console ^11.0 -> satisfiable by illuminate/console[11.x-dev (alias of dev-master)]. - Root composer.json requires laravel/framework ^10.17 -> satisfiable by laravel/framework[v10.17.0, ..., 10.x-dev].
