Hi Simon, This error is a bug caused by not having a ROS path (in the settings). It should not impact anything. You can remove this error for now by filling in the path to your ROS distribution (in your case /opt/ros/melodic) in the ROS settings. This error will not pop up in future versions at all as it has been fixed (issue #49 dealt with it)

I hope this helps deal with the error popup

Thanks for the reply! I'm an absolute newbie to ros. Where do I find the ROS settings?

Noam-Dori commented 3 years ago

You can find the ROS settings in Settings->Languages & Frameworks->ROS You can find detailed documentation on the settings page on the wiki
