I am trying to generate custom ROS messages using rosgenmsg() following the link below.
However, Matlab keeps telling me
"Could not install the required python packages. "
"ros.internal.createOrgetLocalPython(); % ensure python is available"
IN addiiton, my default python version is 3.8 and I have changed it to 2.7 by using
pyenv('Version','/usr/bin/python2.7'), where /usr/bin/python2.7 is the full path of my python executable.
