when used roslaunch m2wr_description spawn.launch the error:

ERROR: cannot launch node of type [gazebo_ros/spwan_model]: Cannot locate node of type [spwan_model] in package [gazebo_ros]. Make sure file exists in package path and permission is set to executable (chmod +x)

when tried rospack find gazebo_ros it returned /opt/ros/noetic/share/gazebo_ros . In gazebo_ros I couldn't find spawn_model.

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.
