Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires orchestra/testbench 10.* -> satisfiable by orchestra/testbench[10.x-dev]. - orchestra/testbench 10.x-dev requires phpunit/phpunit ^11.5.3 -> found phpunit/phpunit[11.5.3, 11.5.4, 11.5.x-dev] but it conflicts with your root composer.json require (10.*). Problem 2 - Root composer.json requires laravel/framework 12.* -> satisfiable by laravel/framework[12.x-dev (alias of dev-master)]. - Root composer.json requires livewire/livewire ^3.0 -> satisfiable by livewire/livewire[v3.0.0-beta.1, ..., v3.5.18]. - illuminate/validation[v10.0.0, ..., 10.x-dev] require illuminate/support ^10.0 -> found illuminate/support[v10.0.0, ..., 10.x-dev] but it conflicts with your root composer.json require (^11.0 | ^12.0). - livewire/livewire[v3.0.2, ..., v3.3.4] require illuminate/support ^10.0 -> found illuminate/support[v10.0.0, ..., 10.x-dev] but it conflicts with your root composer.json require (^11.0 | ^12.0). - illuminate/validation[v9.0.0-beta.1, ..., 9.x-dev] require illuminate/support ^9.0 -> found illuminate/support[v9.0.0-beta.1, ..., 9.x-dev] but it conflicts with your root composer.json require (^11.0 | ^12.0). - livewire/livewire[v3.0.0-beta.1, ..., v3.0.0-beta.6] require illuminate/validation ^9.0|^10.0|^11.0 -> satisfiable by illuminate/validation[v9.0.0-beta.1, ..., 9.x-dev, v10.0.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev]. - livewire/livewire[v3.0.0-beta.7, ..., v3.5.18] require illuminate/validation ^10.0|^11.0 -> satisfiable by illuminate/validation[v10.0.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev]. - Only one of these can be installed: illuminate/validation[v9.0.0-beta.1, ..., 9.x-dev, v10.0.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev], laravel/framework[dev-master]. laravel/framework replaces illuminate/validation and thus cannot coexist with it. - laravel/framework 12.x-dev is an alias of laravel/framework dev-master and thus requires it to be installed too.
