Hi

I'm trying to get familar with the ROS toolbox, but so far I can't get it up and running in Matlab. I'm trying to initialize ROS with the command 'rosinit' and get the following error.

>> rosinit

Adding required Python packages to virtual environment....Done.
Could not install the required Python packages. System error message: Collecting catkin_pkg

. Use pyenv function to set the path to the Python executable and retry the command.
 

I already have installed python 2.7 and running 'pyenv' the following is shown.

>> pyenv
ans =
