已经写了一个pr，这个bug将在下个版本被修复
若需要的话，可以先看看pr的内容，自行修改源码

目前是否解决？7.27使用pip安装库后依旧出现#145问题，
测试时，库中
D:\Anaconda\lib\site-packages\graia\application\event\lifecycle.py
无法正常运行
ImportError: cannot import name 'BaseDispatcher' from 'graia.broadcast.entities.event' (D:\Anaconda\lib\site-packages\graia\broadcast\entities\event.py)

有问题的话可以先回退版本
