Class 未找到 CacheItemPoolInterface Symfony

Class CacheItemPoolInterface not Found Symfony

我正在使用 api-平台和 Symfony。它在本地完美运行,但是当我将它部署在 PREPROD 服务器上时,出现以下错误。

我完全不知道问题出在哪里。我接受任何提示谢谢!

Invalid service "cache.app": class Psr\Cache\CacheItemPoolInterface not found.

我认为错误是由于您的生产配置而引发的,具体取决于 Symfony Cache component

尝试明确要求它:

composer require symfony/cache

如果您收到它已经隐式安装的消息,它可能在生产环境中被禁用。
