Your requirements could not be resolved to an installable set of packages. Problem 1 - illuminate/console 11.x-dev is an alias of illuminate/console dev-master and thus requires it to be installed too. - Conclusion: don't install illuminate/console dev-master (conflict analysis result) - Only one of these can be installed: laravel/framework[dev-master, v7.20.0, ..., 7.x-dev, v8.19.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev, v10.17.0, ..., 10.x-dev], illuminate/contracts[v10.0.0, ..., 10.x-dev]. laravel/framework replaces illuminate/contracts and thus cannot coexist with it. - Only one of these can be installed: laravel/framework[dev-master, v7.20.0, ..., 7.x-dev, v8.19.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev, v10.17.0, ..., 10.x-dev], illuminate/view[dev-master]. laravel/framework replaces illuminate/view and thus cannot coexist with it. - laravel/framework 11.x-dev is an alias of laravel/framework dev-master and thus requires it to be installed too. - Root composer.json requires illuminate/console ^11 -> satisfiable by illuminate/console[11.x-dev (alias of dev-master)], laravel/framework[11.x-dev (alias of dev-master)]. - Root composer.json requires illuminate/contracts ^10 -> satisfiable by illuminate/contracts[v10.0.0, ..., 10.x-dev], laravel/framework[v10.17.0, ..., 10.x-dev].
