when i trying to launch navigate I am facing an issue while trying to launch the map_server and amcl nodes. Despite following the recommended steps and troubleshooting techniques, I have been unable to resolve the problem.
The specific error I am encountering is as follows:
ERROR: cannot launch node of type [map_server/map_server]: Cannot locate node of type [map_server] in package [map_server]. Make sure the file exists in the package path and the permissions are set to executable (chmod +x).
ERROR: cannot launch node of type [amcl/amcl]: Cannot locate node of type [amcl] in package [amcl]. Make sure the file exists in the package path and the permissions are set to executable (chmod +x).
I have ensured that the ROS_PACKAGE_PATH includes the necessary paths, sourced the ROS environment using source /opt/ros/noetic/setup.bash, and verified the node names and package installations, and allowed executing nodes.

However, the issue persists.

It's solved by "catkin_build".
