Version incompatibility with pip and rasa

I tried to follow the instructions on this repo coz I wan't to play around it a little bit:

make install
python -m pip install --upgrade "pip<20"

I understand that this is incompatible with the latest version of rasa.

My rasa version is:

Rasa Version : 3.4.1 Minimum Compatible Version: 3.0.0 Rasa SDK Version : 3.4.0 Python Version : 3.9.2 Operating System : Linux-5.10.0-21-amd64-x86_64-with-glibc2.31 Python Path : /usr/bin/python3

architecture: 5.10.0-21-amd64 4 GB / 2 AMD CPUs 80 GB NVMe SSDs 4 TB transfer

Is there any way that I can at least run this successfully, even with an isolated environment or OS with the minimum requirement? What can I do to make this work?

Thank you very much,

Bob
