graia是mirai的一个python库
网上也有很多配置教程但我在使用的过程中任然会碰到许多他们没有讲到的问题，在找到官方群问明白之后觉得和大家分享一下如何解决这些问题

1.mah和mcl版本不适配问题

为了演示错误找了1.0.3的mcl和2.0.2的mah
目前最稳定的版本是1.0.5的mcl和1.12.0mah
下载地址为https://github.com/iTXTech/mirai-console-loader/releases/tag/v1.0.5和https://github.com/project-mirai/mirai-api-http/releases/tag/v1.12.0
使用的话个人看来好像不需要有些教程那么麻烦
将正确的版本的mcl和mah下载之后，cd到mcl路径输入mcl，看到最后mirai-console started successfully.输入exit关闭。然后把mah放到plugins里面之后再次启动mcl就可以了

2.控制台里正常输出没有红字报错，但在python运行实例时出现导入错误
请使用
这个对python版本好像也有要求，选择python3.8以上的版本比较好，否则会出现导入错误比如她的这个ImportError: cannot import name ‘BaseDispatcher’ from ‘graia.broadcast.entities.event’
pip下载graia-application-mirai的时候不要懒请手动指定版本

可以获取机器人所在的群聊发送的闪照和群友撤回的消息，其他的一些接口挺有趣的就加上去了（虽然没什么用）
