ROS required python packages

I am attempting to execute rosinit on MacOS with MATLAB 2021b. I recieve an error message: "Could not install the required Python packages. System error message: bash:"

If I run pyenv('Version','/usr/bin/python') I see the following:

Version: "2.7"

Executable: "/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python"

Library: "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib"

Home: "/System/Library/Frameworks/Python.framework/Versions/2.7"

Status: NotLoaded

ExecutionMode: InProcess

What needs to be installed/modified in order to get the necessary python packages to be installed by MATLAB?

Your python installation looks good for ROS. What is the detail of the error message?
