I'm very new to ROS and when I try to launch the 'rosinit' command on my M1 mac i receive the following message/error:
>> rosinit
Launching ROS Core...
Adding required Python packages to virtual environment..chmod: /Users/mattiawaitz/.matlab/R2021a/ros1/maci64/venv/bin/activate: No such file or directory

Done.
Could not install the required Python packages. System error message: bash:

. Use pyenv function to set the path to the Python executable and retry the command.
I've installed Python 2.7 as requested by the help page and already tried using the 'pyenv' command as suggested by MATLAB in the last line.

Can you try the following once and let me know ?
>> pyenv('Version',<path to python 2.7>);
>> ros.internal.createOrGetLocalPython(true);
>> rosinit
Thanks and regards,
Jagadeesh

Sorry for the continuous disturb, but I have one last question: how can I retrieve the maci version? I downloaded the 2.7.18 from python.org, which I assume is an intel version especially since it dates back to early 2020. As far as the path goes, the command I write down is the following
>> pyenv('Version','/Applications/Python2.7');
which returns a message saying that it can't find any valid executable.
Again sorry for the disturb and thanks for the kind responses.

Hi Mattia,
I think it is installed in /usr/local/bin.
So, try the following. It should work
>>pyenv("Version","/usr/local/bin/python")
