我从4.4升级Symfony项目时遇到问题。到5.0。我已经删除了所有的折旧等，现在正试图通过作曲家升级。

运行composer update“symfony/*”时，出现以下错误：

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

  Problem 1
    - Conclusion: remove stof/doctrine-extensions-bundle v1.6.0
    - Conclusion: don't install stof/doctrine-extensions-bundle v1.6.0
    - Conclusion: don't install symfony/console v5.0.11
    - Conclusion: don't install symfony/console v5.0.10

    - Conclusion: don't install symfony/console v5.0.1
    - stof/doctrine-extensions-bundle v1.6.0 requires symfony/http-kernel ^4.4 || ^5.2 -> satisfiable by symfony/http-kernel[v4.4.21].
    - symfony/console v5.0.0 conflicts with symfony/http-kernel[v4.4.21].
    - symfony/console v5.0.0 conflicts with symfony/http-kernel[v4.4.21].
    - Installation request for symfony/console 5.0.* -> satisfiable by symfony/console[v5.0.0, v5.0.1, v5.0.10, v5.0.11, v5.0.2, v5.0.3, v5.0.4, v5.0.5, v5.0.6, v5.0.7, v5.0.8, v5.0.9].

看起来symfony/console和symfony/http内核有问题。当我在packagist上检查stof/doctrine扩展包时，我在symfony/console上找不到任何限制。对于symfony/http内核，看起来至少需要5.2版本，但是，我不想直接升级到symfony 5.2，或者这是唯一可以解决这个问题的方法吗？是否有人看到/知道这个问题的来源，并能为我指出正确的方向？

这是我的composer.json：
