在作曲家更新以修复我的应用程序使用的软件包上的一些漏洞后，我处理了一个错误：
服务"sensio_framework_extra.controller.listener"依赖于不存在的服务"annotation_reader">
如本答案所示，我尝试添加doctrine/annotations包，但它没有解决我的问题(包似乎已经安装(。
λ composer require doctrine/annotations

编辑： 我正在使用所有框架，我已经手动删除了缓存以确保没有问题。我也重新启动了我的开发计算机。最后，我通过将我的 github 项目部署到另一个目录中来解决这个问题，应用程序工作正常。我不关闭这个问题，因为我想在生产中出现问题时找到问题。
由于教义(或教义/注释(本身不注册服务(为什么会这样(，我查找了教义包，doctrine/doctrine-bundle提供了annotation_reader服务：https://github.com/doctrine/DoctrineBundle/blob/af8ac792c9b970ff2bc25b49ab9b31afd9e03dbf/Resources/config/orm.xml#L82
我在尝试创建新设置时遇到了非常相似的错误(The service "doctrine.orm.default_annotation_metadata_driver" has a dependency on a non-existent service "annotation_reader".(。 我记录了一些说明，并在学说之前尝试过作曲家安装ormfixtures(--dev(。 一旦我以正确的顺序完成此操作，一切都按预期进行。
我的具体示例来自 Twilio 的说明，其中按以下顺序包含以下命令：
composer req --dev maker ormfixtures fakerphp/faker
composer req doctrine twig
当我将它们反转为以下顺序时，它起作用了：
composer req doctrine twig
composer req --dev maker ormfixtures fakerphp/faker
我在 Symfony 4.4 的作曲家更新后遇到了同样的问题。 这是因为我用"教义\持久性"代替了"Doctrine\Common"，而不是"Doctrine\Common\Persistence"。
换句话说：不管你为什么会出现这个错误，它来自代码中一个损坏的命名空间。
