Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires nova-kit/nova-devtool ^1.0 -> satisfiable by nova-kit/nova-devtool[v1.0.0, ..., 1.x-dev]. - laravel/framework[v8.0.0, ..., v8.11.2] require php ^7.3 -> your php version (8.0.30) does not satisfy that requirement. - Only one of these can be installed: illuminate/support[dev-master, v5.2.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev, v10.0.0, ..., 10.x-dev], laravel/framework[v8.0.0, ..., 8.x-dev]. laravel/framework replaces illuminate/support and thus cannot coexist with it. - Conclusion: install illuminate/support v9.52.16 (conflict analysis result) - Root composer.json requires laravel/framework ^8.0 -> satisfiable by laravel/framework[v8.0.0, ..., 8.x-dev]. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
