Cannot roslaunch

[BKC92]

Hi Raza An error occurred while following your project, but I couldn't figure it out even after searching, so I asked this question. My problem is that when I run roslaunch, the following error appears and ends with keyboardinterrupt. I would be very grateful if you could tell me how to fix the error.

Seems to be an error of the ROS executor not able to find the binaries for all the node .py nodes in the current workspace overlay.

Try:

1. Building the ROS workspace again
2. Set the permissions for all the .py node by running: chmod +x <filename>.py
3. Source the workspace

Then try to launch the launch file again.

Closing due to no activity.
