DoctrineFixturesBundle 从 Symfony 5.1 升级到 5.2 的问题
Problems with DoctrineFixturesBundle upgrading from Symfony 5.1 to 5.2
我正在将我的 Symfony 4.4 项目升级到 Symfony 5.4（当前的 LTS 版本）。我试过修改 composer.json，直接强制到 5.4 版本，但是我发现了很多依赖问题，所以我慢慢地“解决”了这个迁移：我移动到 5.0，然后到 5.1，现在我'我正在尝试从 5.1 迁移到 5.2，但我有依赖性问题，我不知道如何解决它们。

我想问题出在软件包 doctrine/doctrine-fixtures-bundle 上，但我不确定，因为我发现很难解释错误消息。这是有问题的包裹吗？如果有，有什么办法可以升级吗，或者我应该删除它，升级应用程序然后重新安装？
我需要这个包，因为我在 运行 测试时用它来填充测试数据库，但也许有任何更新的包可以用于这项工作？

我不知道这能帮上什么忙，但这个应用程序最初是一个 Symfony 3.4 应用程序，几年前我升级到 Symfony 4.4，现在我正在努力迁移到 5.4...
问题是您在 v2 中需要 doctrine/common。这取决于 v1 中的 doctrine/persistence。将所有包更新到 Symfony 5.2 也会将 symfony/doctrine-bridge 更新到 5.2 - 这需要 v2 中的 doctrine/persistence。
将 composer.json 中的 doctrine/common 更新到 v3 可能有助于解决问题。此外，由于您已经在使用 symfony/flex，您可以删除 Symfony 包上的所有显式版本限制 - 像您已经做的那样在 extra 部分进一步定义 Symfony 版本就足够了。这使得更新所有 Symfony 包变得更容易，因为你只需要更改这一行
