Hi @esteve , thanks for the sharing. I'm trying to build the macOS example with :

src/ament/ament_tools/scripts/ament.py build --isolated

But got an error:

Traceback (most recent call last):
File "src/ament/ament_tools/scripts/ament.py", line 139, in
from ament_tools.package_types.ament import entry_point_data as ament_entry_point_data # noqa
File "/Users/yue.li/ros2_objc_ws/src/ament/ament_tools/ament_tools/package_types/ament.py", line 15, in
from catkin_pkg.package import package_exists_at
ModuleNotFoundError: No module named 'catkin_pkg'

What's wrong with this, and what should I do?
