没有找到休息包类

Question

我使用FOSRest Bundle与FOSUser一起使用API​​创建注册表单。 当我调试FOSRestController.php时，收到此消息：

  

致命错误：类   找不到'Symfony \ Bundle \ FrameworkBundle \ Controller \ Controller'   d：\ e-electricity.com \厂商\ friendsofsymfony \其余束\ FOS \ RestBundle \控制器\ FOSRestController.php   第24行

我尝试使用composer update来删除缓存，但我仍然收到相同的消息。
