Can not launch node of type [robot_pose_ekf/robot_pose_ekf]: Cannot locate node of type [robot_pose_ekf] in package [robot_pose_ekf]
I use the robot_pose_ekf, but when I Run the robot pose ekf use $ roslaunch robot_pose_ekf.launch the error info as the following.
ERROR: cannot launch node of type [robot_pose_ekf/robot_pose_ekf]: Cannot locate node of type [robot_pose_ekf] in package [robot_pose_ekf]. Make sure file exists in package path and permission is set to executable (chmod +x)
