Rasa installation error pip 20.2

Hi, I’m trying to re-install rasa because I changed my python version, but I’m getting the error in the picture. I downgraded the pip version to 20.2 and tried to reinstall but it didn’t work. I’ll be happy if you can help me.

In addition, when I want to train, I get an error like this.

rasa --version Rasa Version : 2.8.12 Minimum Compatible Version: 2.8.9 Rasa SDK Version : 2.8.2 Rasa X Version : None Python Version : 3.8.10 Operating System : Windows-10-10.0.19041-SP0 Python Path : c:\python\python.exe

@grigrigrigon please update the rasa-sdk to at least 2.8.9 or for more stable version rasa and rasa-sdk = 2.8.1
