Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires php ^8.1 but your php version (8.0.30) does not satisfy that requirement. Problem 2 - Root composer.json requires brianium/paratest ^6.6 -> satisfiable by brianium/paratest[v6.6.0, ..., 6.x-dev]. - symfony/process[v6.1.0-BETA1, ..., 6.4.x-dev] require php >=8.1 -> your php version (8.0.30) does not satisfy that requirement. - laravel/framework[v9.0.0-beta.1, ..., 9.x-dev] require symfony/process ^6.0 -> satisfiable by symfony/process[v6.0.0-BETA1, ..., 6.4.x-dev]. - You can only install one version of a package, so only one of these can be installed: symfony/process[v4.3.4, ..., 4.4.x-dev, v5.0.0-BETA1, ..., 5.4.x-dev, v6.0.0-BETA1, ..., 6.4.x-dev, v7.0.0-BETA1, ..., 7.2.x-dev]. - Conclusion: install symfony/process v5.4.40 (conflict analysis result) - Root composer.json requires laravel/framework 9.* -> satisfiable by laravel/framework[v9.0.0-beta.1, ..., 9.x-dev]. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
