I am trying to run rosinit but I get this error:

"Path to Python Executable is not set. Set the path to the Python executable using ROS Toolbox preferences"

and when I give the correct path, it doesnt work and I get this error: (Although the correct version is specified)

How to solve it?

Im using R2022b

Hello Nabil,

Sorry about the confusing error message, team is working on improving this error message.

As for now, please try to install and provide the path to python3.9.13 in "ROS Toolbox preferences".

Hope this helps,

Thanks,

Josh

Thanks again for following up.

Yes I made same steps to download python3.9.13 and I got at the end the file in the above screenshot. Even if I followed your tutorial (which is what I did), which file should I choose in the ROS Toolbox Preferences to make it work.

Oh I see.

If you run

$ which python3

$ which python3.9

on your linux terminal, are you able to see an output? If yes, you can choose that file in the ROS Toolbox Preferences.
