I created a launch file that contains:

  <param name="/use_sim_time" value="true"/>
  <node pkg="map_server" type="map_server" name="map_server_node" args="/home/maysam/fuerte_workspace/sandbox/mit/map.yaml"/>

But the output is:

ERROR: cannot launch node of type [map_server/map_server]: can't locate node [map_server] in package [map_server]

I can run the node manually and successfully:

rosrun map_server map_server /home/maysam/fuerte_workspace/sandbox/mit/map.yaml

Try the command: roscd map_server to check which folder that your map_server node is using. If it is not the folder you are after, just delete that folder. I have two projects, and when I launch one of them, it used the map server from another project, then I got this issue.

Under melodic on Ubuntu, you would

sudo apt-get install ros-melodic-map-server
