. Use pyenv function to set the path to the Python executable and retry the command.
/opt/homebrew/Caskroom/miniforge/base/envs/matlab_ros/bin/python -m pip install pyyaml and /opt/homebrew/Caskroom/miniforge/base/envs/matlab_ros/bin/python -m pip install pyyaml==5.4.1 make no sense.

Hmm, I've not seen this exact issue before. One thing that has helped other similar issues is to upgrade pip and setuptools in the base Python installation. So in a terminal outside of MATLAB run:
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade setuptools
After doing that, you can force recreation of the virtual environment in MATLAB by running this from the Command Window. Make sure pyenv is set the same way first (to the base executable).
ros.internal.createOrGetLocalPython(true)

Hi Yang,
Could you let us know whether the python in '/opt/homebrew/opt/python@3.9/bin/python3.9' is arm64 or x86_64 version. To know which architecture of python you are using, execute the following command:
!file /opt/homebrew/opt/python@3.9/bin/python3.9
The error seems to be occurring with the native python (arm64). You could install a intel or universal python as alternative from the official python 3.9.10 release for macos: https://www.python.org/downloads/macos/.

Hi! Is MATLAB ROS stable on Mac Silicon? I am considering upgrading. Thanks!
