[MM3-users] Not able to start mailman server

Hi,

I am trying to start the mailman server on a mac according to the instructions given on the website as shown -

$(py3) git clone git@gitlab.com:mailman/mailman.git $(py3) cd mailman $(py3) python setup.py develop

$(py3) mailman start $(py3) cd ..

But I run into the following problem -

Starting Mailman's master runner Generating MTA alias maps /usr/local/Cellar/python@3.9/3.9.5/bin/python3.9: can't open file '/usr/local/opt/python@3.9/bin/master': [Errno 2] No such file or directory

Can anyone help me out with this?

Thanks, Kartheek
