Your requirements could not be resolved to an installable set of packages. Problem 1 - laravel/framework[v8.0.0, ..., v8.11.2] require php ^7.3 -> your php version (8.0.30) does not satisfy that requirement. - Root composer.json requires nova-kit/nova-devtool ^1.0 -> satisfiable by nova-kit/nova-devtool[v1.0.0, ..., 1.x-dev]. - Root composer.json requires whitecube/nova-flexible-content ^1.1 -> satisfiable by whitecube/nova-flexible-content[v1.1.0, v1.1.1]. - whitecube/nova-flexible-content[v1.1.0, ..., v1.1.1] require laravel/framework ^8.0|^9.0|^10.0|^11.0 -> satisfiable by laravel/framework[v8.0.0, ..., 8.x-dev]. - Only one of these can be installed: illuminate/support[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, v11.0.0, ..., 11.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) Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
