SymfonyでDoctrinの環境構築で詰まってます。

composer require symfony/orm-pack

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laminas/laminas-code 3.4.1 requires php ^7.1 -> your php version (8.0.12) does not satisfy that requirement.
    - symfony/proxy-manager-bridge v5.3.4 requires friendsofphp/proxy-manager-lts ^1.0.2 -> satisfiable by friendsofphp/proxy-manager-lts[v1.0.5].
    - friendsofphp/proxy-manager-lts v1.0.5 requires laminas/laminas-code ~3.4.1|^4.0 -> satisfiable by laminas/laminas-code[3.4.1].
    - symfony/proxy-manager-bridge is locked to version v5.3.4 and an update of this package was not requested.

You can also try re-running composer require with an explicit version constraint, e.g. "composer require symfony/orm-pack:*" to figure out if any version is installable, or "composer require symfony/orm-pack:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
