Problem isn't the package, it was the python executable. If there is none, nothing can be imported. Problem is solved.

That's strange. What output do you get when running the following command?

python -c 'import em; print(em.__file__)'

Yes, the Python Version is set to 3. The problem is maybe that the python executable in /catkin_ws/build/python3 is missing, that should be the purpose why the module couldn't be found.

Is it trying to use python2 for the empy module and hence not finding it? Are you sure you set the env variable ROS_PYTHON_VERSION to 3 when compiling the base ROS? You can check it in /opt/ros/melodic/etc/catkin/profile.d/

-- Using default Python package layout

CMake Error at /opt/ros/melodic/share/catkin/cmake/empy.cmake:29 (message):
  Unable to find either executable 'empy' or Python module 'em'...  try

Same issue had someone with indigo.

It seems to work fine for me, I'm able to run catkin_make on my workspaces to build. Can you show me what error you get?

Also, looking at the source, catkin doesn't require an empy executable, it has an option to use the module as well (

This pacakge doesn't work with catkin_make as it doesn't have an executable. Could you please add the one from debian sid?
