@grafst I think python 3.7.0 is the lowest version supported for using libraries with CPython.

Mine is a little newer than that, and pip installs typing-extensions 4.5.0 for me:

❯ python --version
Python 3.10.6

~ 
❯ pip install typing-extensions~=4.0
Defaulting to user installation because normal site-packages is not writeable

Try using python 3.7+ if you can.

compiling python 3.8 (since there is no package for it on raspbian 9) from scratch fixed the issue for me

thanks @FoamyGuy

Closing. Seems resolved using a newer CPython release.
