JmsSerializerBundle 安装以错误结束：“jms_serializer.visitors”下的无法识别选项“xml”

Question

当我安装 Symfony 4 框架项目并添加 JmsSerializerBundle 时，出现错误。

复制：

composer create-project symfony/website-skeleton myproject
cd myproject
composer require jms/serializer-bundle

安装以错误结束：

在 Windows 10 Powershell 上运行 composer 等。我猜骨架太裸露了，需要依赖，但不应该自动解决吗？

可能是什么原因？我该如何解决？提前感谢您的帮助。

当前配方与 JMSSerializerBundle 3 不兼容（有一个待处理的拉取请求，请参阅 https://github.com/symfony/recipes-contrib/pull/559）。所以现在，您需要手动调整配置。
