There are no errors - there is some output that looks like an error, but it is not. Your package builds successfully as far as I can tell. Regarding the Python3 issue, please see our https://robostack.github.io/FAQ.html |

Issue
Hey Team,
I have trouble with compiling a customized msg or srv on M2 Mac. Before reporting this bug, I deeply test out the current solution provided #149, but failed to resolve the problem. Hence, I am going to elaborate my trails and hoping to hear back from you. THANKS IN THE ADVANCE!
Background
Package and msg
I mainly follow the official tutorial to customize the msg with ROS2 humble. My package called
py_exampleandmsg/Sphere.msgis showing belowCMakeLists.txt
package.xml
The terminal command lines that I am using for all later trails.
Error Outputs:
