Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires illuminate/bus ^10.0 -> satisfiable by illuminate/bus[v10.0.0, ..., 10.x-dev]. - laravel/framework 11.x-dev is an alias of laravel/framework dev-master and thus requires it to be installed too. - Only one of these can be installed: laravel/framework[dev-master], illuminate/bus[v10.0.0, ..., 10.x-dev]. laravel/framework replaces illuminate/bus and thus cannot coexist with it. - Root composer.json requires laravel/framework 11.* -> satisfiable by laravel/framework[11.x-dev (alias of dev-master)].
