ROS cannot find a node [closed]

edit

I have successfully installed teb_local_planner on my machine using 'sudo apt-get install ros-kinetic-teb-local-planner'. This package includes the test_optim_node node, and I can look up the node under /opt/ros/kinetic/lib/teb_local_planner.

The trouble comes when I try running the node, 'rosrun teb_local_planner test_optim_node'. ROS knows where the package, 'teb_local_planner' is, but cannot locate the node 'test_optim_node'. There must be a simple way to fix this problem, but I do not know how.

I have also tried cloning teb_local_planner from GitHub, but I cannot build the package from the source, because of an error that I have trouble resolving.
