Did you install rasa into a virtual environment? If you used a Conda environment you might still need to activate it with conda activate name_of_your_rasa_environment.
Also, I understand the pain of installing rasa on mac. What worked for me was using Python 3.7 instead (I used pyenv to set that up). I am not quite sure what it is with Python 3.9 that causes installation issues. If you don’t prefer Python 3.9 for any particular reason, then I wouldn’t recommend wasting time trying to figure out why this is happening and just downgrade to 3.7.
thx for the tip, i think i’ll try downgrade python to 3.7
and about rasa version i didn’t choose the version when i installed i only prompt the command ‘pip install rasa’ simply
When installing through pip, you should get version 2.3.0.
Please check the installed packages with pip again to make sure you don’t have a super old version of Rasa.
