Revision history [back]

There is a typo in the launch file. The node is called spawn_model, the error says spwan_model. I assume you've created the launch file yourself. If you've copy-pasted the contents, you should probably let The Construct know they have a faulty tutorial.

Also note that the executable is in /opt/ros/noetic/lib/gazebo_ros/. In share there are no headers, libs or executables (usually). There are configs (e.g. cmake, ROS config), launch files, etc.
