laravel枚举类创建

大家好，我想请教一下，php的laravel是怎么使用枚举类的，百度上查询都是千篇一律的，是使用这个composer require bensampo/laravel-enum命令来安装依赖库的，但是我使用该命令报错了

Using version ^3.0 for bensampo/laravel-enum
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1

Installation failed, reverting ./composer.json to its original content.

我想请教一下这个问题该怎么解决，或者说有其他的方法来创建枚举类吗？
