Installing RASA through pip3

I had a similar issue when installing Rasa on Kali with Python 3.11.2. What worked for me was creating a virtual environment with Python 3.9, since Rasa seems to have better compatibility with that version. After setting up the virtual environment, I activated it and ran the install command again, and it went through fine. You might want to give that a shot and see if it fixes the problem!
