ROS Melodic catkin_make fail

1.6k Views Asked by At

So my catkin_make fails with error AttributeError: 'module' object has no attribute 'Interpreter' As I searched for a solution I found that the problem is that there is a confusion between the em and the empy packages, so I proceeded to remove the em package as advised, but the error still persists.

You need to uninstall the em and install the empy package.

pip uninstall em

pip install empy
