我尝试安装并使用带有Category实体的扩展Tree Gedmo，但是当我添加新类别时，我有这样的错误：
无法手动更改Root，而是更改父级
500内部服务器错误 - UnexpectedValueException。
我已按照此链接操作，并按指示执行了所有操作：https://github.com/Atlantic18/DoctrineExtensions/blob/master/doc/symfony2.md
我创建了 app / config / doctrine_extensions.yml 和 src / Project / StoreBundle / Listener / DoctrineExtensionListener.php
应用/ conifg.yml
