Rasa and compatibly with Python's versions

i just started developing my assistant with Rasa and i couldn’t install Rasa on Python3.9 ,and the solution that worked for me is to downgrade Python to 3.7

can this problem be solved ,because i need everything i’m working and developing with is up-to-date

I recommend you to use Python virtual environments.

Rasa has a lot of dependencies, which in turn have a lot of dependencies. I understand why they haven’t upgraded to Python 3.9 yet.

By the way, you can use Python 3.8 with the current version of Rasa. Not necessarily 3.7.
