If rosrun cannot locate the move_base node in the move_base package, then it is likely that the built version of the move_base package is not on the ROS_PACKAGE_PATH.

Make sure the move_base package is on the ROS_PACKAGE_PATH (an environment variable). If it still doesn't work, then please post your ROS_PACKAGE_PATH and your CMAKE_PREFIX_PATH.

I have the same problem as the topic starter. I use ROS Indigo on Ubuntu 14.04 virtual machine. I installed the navigation stack and now I try to run move_base node. Rosrun sees the move_base pack, but it seems to be no move_base node inside it. I checked ROS_PACKAGE_PATH and CMAKE_PREFIX_PATH, here is the answer:

viki@c3po:~$ echo $CMAKE_PREFIX_PATH /home/viki/catkin_ws/devel:/opt/ros/indigo viki@c3po:~$ echo $ROS_PACKAGE_PATH /home/viki/catkin_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks

There is no stacks folder in Indigo directory. But there is a folder called move_base in share directory. I am very new to ROS and Ubuntu, so I have no idea what can cause the problem, please help me!
