问题描述
我是 symfony 4 的新手，我尝试通过 composer require admin 命令安装管理面板，但听起来错误：
Executing script cache:clear [KO]
[KO]
Script cache:clear returned with error code 1

Script @auto-scripts was called via post-update-cmd
Installation Failed,reverting ./composer.json and ./composer.lock to their original content.
解决方法
一个似乎解决了这个问题的新提交今天合并到了存储库 EasyCorp/EasyAdminBundle 中。 在他们发布下一个版本之前，你可以这样做
symfony composer req admin:3.0.x-dev
