Invalid type annotation

[wj-Mcat]

When I clone the code from master branch, Invalid type annotation occures.

File "/Users/wujingwujing/Downloads/temp/python-wechaty/src/wechaty/types.py", line 43, in Sayable: Invalid type annotation '<instance of module>' for return [invalid-annotation]
  Not a type
File "/Users/wujingwujing/Downloads/temp/python-wechaty/src/wechaty/types.py", line 43, in Sayable: Invalid type annotation '<instance of module>'

File "/Users/wujingwujing/Downloads/temp/python-wechaty/src/wechaty/types.py", line 43, in Sayable: Invalid type annotation '<instance of module>' for reply_to [invalid-annotation]

But this error don't occure at github action.

I did not see the above information when I clone the repo, with:

git clone https://github.com/wechaty/python-wechaty

So is the problem still exist? Or how to reproduce the case?
