I got the error trying to build the package that I created using the instruction available on http://wiki.ros.org/ROS/Tutorials/ RosWiki
I am also trying to understand the folder structure and I am a noob trying to get into this field of robotics and everyone points to ROS and this is getting frustrating because I can’t create a simple package and get to scripting.

I am running M3 Mac, let me know if you need anything else from me to help me troubleshoot this. Thanks. I installed ROS using conda following instruction on this website:
