from graia.application import GraiaMiraiApplication, Session出现错误

[3akura]

报错内容：
Traceback (most recent call last):
File "D:/qqbot/qqbotpy/qqbot.py", line 2, in
from graia.application import GraiaMiraiApplication, Session
File "D:\python3\lib\site-packages\graia\application_init_.py", line 14, in
import graia.application.event.mirai # for init events
File "D:\python3\lib\site-packages\graia\application\event\mirai.py", line 1, in
from typing import Any, Dict, Literal, NoReturn, Optional
ImportError: cannot import name 'Literal' from 'typing' (D:\python3\lib\typing.py)

报错的语句是mirai.py文件中的：“from typing import Any, Dict, Literal, NoReturn, Optional”，Any, Dict, NoReturn, Optional都在typing.py文件中，都正常，Literal在typing.pyi文件中，import失败

应该怎么解决

版本问题，不要用最新版，建议graia用0.19x，broadcast用0.8x
