我嘗試在 Symfony 5.1 項目中安裝 Doctrine ORM，但出現(xiàn)以下錯誤：composer require symfony/orm-packUsing version ^1.1 for symfony/orm-pack./composer.json has been updatedLoading composer repositories with package informationUpdating dependencies (including require-dev)Restricting packages listed in "symfony/symfony" to "5.1.*"Your requirements could not be resolved to an installable set of packages.  Problem 1    - doctrine/doctrine-migrations-bundle v2.0.0 requires symfony/framework-bundle ~3.4|~4.0 -> no matching package found.    - Installation request for symfony/orm-pack ^1.1 -> satisfiable by symfony/orm-pack[v1.1.0].    - Conclusion: remove doctrine/doctrine-migrations-bundle 3.0.1    - Conclusion: don't install doctrine/doctrine-migrations-bundle 3.0.1    - symfony/orm-pack v1.1.0 requires doctrine/doctrine-migrations-bundle ^2 -> satisfiable by doctrine/doctrine-migrations-bundle[2.1.0, 2.1.1, 2.1.2, v2.0.0].    - Can only install one of: doctrine/doctrine-migrations-bundle[2.1.0, 3.0.1].    - Can only install one of: doctrine/doctrine-migrations-bundle[2.1.1, 3.0.1].    - Can only install one of: doctrine/doctrine-migrations-bundle[2.1.2, 3.0.1].    - Installation request for doctrine/doctrine-migrations-bundle (locked at 3.0.1) -> satisfiable by doctrine/doctrine-migrations-bundle[3.0.1].Potential causes: - A typo in the package name - The package is not available in a stable-enough version according to your minimum-stability setting   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details. - It's a private package and you forgot to add a custom repository to find itRead <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.Installation failed, reverting ./composer.json to its original content.我需要什么版本才能在 Symfony 5.1 中使用 Doctrine？我嘗試過安裝composer req doctrine/doctrine-migrations-bundle:2.0composer require symfony/orm-pack:1.1但兩者都失敗了。
