I'm guessing that you're attempting to use roslaunch directly with a node. This isn't possible because roslaunch expects launch files, not nodes. Launch files usually end with the launchfile extension and are XML files. You can launch them similar to
roslaunch <my_package> <my_launch_file.launch>
Take a look at roslaunch on the wiki.
