[PROBLEM] python version

[rafhtl]

I get an error at startup kodi from addon script.embuary.info

script.module.arrow

/home/xbian/.kodi/addons/script.module.arrow/lib/arrow/locales.py", line 19, in <module>
from typing_extensions import Literal
ModuleNotFoundError: No module named 'typing_extensions'

I wrote in the module's forum
https://github.com/Razzeee/script.module.arrow/issues/3

and they tell me I need a python version higher than the one I have.
my versions
Python 2.7.16
Python 3.7.3

can you help me?

thank you
raf

ps. this happend a couple of days ago after updating python via apt-get full-upgrade
