Hi Christina,

Based on the attached build log, I see that python virtual environment is not created properly.

Please check pyenv in your system. Ensure that you are using Python 3.9.

Then do the re-creation of python virtual environment:

ros.internal.createOrGetLocalPython(true);

Then execute rosgenmsg. If the issue still persists, please attach the complete build log.

Thanks

Hari
