python pylint missing dependencies

python pylint missing dependencies

[Brian Inglis]

Hi Marco,

Trying to run python pylint3.6/7/8/9 pylint3.6/7/8 need typing_extensions (see 
at bottom):

	$ pip3.6/7/8 install typing_extensions

as python typing is only available as python{,2,27}-typing, and appears not to 
have been updated to python3:

python-typing                                ORPHANED (Yaakov Selkowitz)

All plus pylint3.9 also need python platformdirs (3.6 not available) (see at 
bottom):

	DEPEND/BUILD_/REQUIRES=python3?-platformdirs

although if defined in DEPEND/BUILD_REQUIRES should be detected by cygport 
python dependency checker IIRC?

Anything I could do to help diagnose or fix this while your system is U/S?

Maybe a dependency no longer required another expected dependency:

Noted. I already built python-typing-extensions
I will upload shortly for 3.8 and 3.9

I have already built platformdirs. It replaces appdirs.
