I accidentally deleted the folder ‘build’ and ‘devel’ in simulation_ws, so I can’t launch the simulation for the realrobot lab. I tried to restore those folder from other rosject but it still did not work. Can someone help me for this ? thanks
Hi, what you can try is simply compile/source again, but it might not work if changes were made. Your best bet is to download the packages you have in your
catkin_ws and fork a new copy of the rosject
Hi, thank you for your suggestion, I’ve tried it and it works now.
