Cannot launch node of type []: can't locate node [] in package []

[mmohmpat]

Hi,

When I try running roslaunch orb_slam2_ros orb_slam2_r200_mono.launch the following error appears
ERROR: cannot launch node of type [orb_slam2_ros/orb_slam2_ros_mono]: can't locate node [orb_slam2_ros_mono] in package [orb_slam2_ros]

Any help troubleshooting the issue? If it an issue with setup then what in particular needs to be changed in the installation to solve this?

Thanks

Duplicate of #29? I still believe this is an error with your installation and is not related to this package. But maybe I'm wrong. Anyone else experiencing this issue?

Do you know what error in installation would cause this? Mismatch in versions or missing packages or similar?

How could I fix this issue?

My guess would be that the ROS workspace variables are not set or set wrong. Try if you find something on Google related to this. This is a generic error and I am almost certain its not related to this package.
