[rospack] Error: package 'usb_cam' not found
Hello,
I had installed from the source usb_cam driver in UBUNTU 18.04 and ROS Melodic.
Built it but now with rosrun usb_cam usb_cam_node (and in parallel roscore in another terminal) I got [rospack] Error: package 'usb_cam' not found (in the folder ~/catkin_ws/src/usb_cam).
How to proceed?
Thanks.
