same problem with python 3.11

[liaozd]

same here, python3.11, and in ubuntu 23.04

I found the solution: downgrading to uiautomator2-2.16.23 could fix it, which depends on packaging-20.9.

For me, cannot fix…… Any updates or other solutions?

[wrzssz]

也可以这样

pip install packaging==21.3

或者降低uiautomator2的版本,或者降低packaging版本

fixed

I am also suffering from this condition. I have downgraded the packaging to 20.9 or downgraded uiautomator2 but the problem still persists. Hope you check it out

[codeskyblue]

uiautomator2 3.x fixed. Because the packaging lib is removed completely
