I created a package inside catkin_ws/src folder using catkin_create_pkg command.

After writing publisher and subscriber nodes, I returned to catkin_ws and run catkin_make. However, I got this error:

            File "/opt/ros/melodic/bin/catkin_make", line 13, in <module>
               from catkin.builder import apply_platform_specific_defaults  # noqa: E402
               ImportError: No module named catkin.builder

I checked the folder catkin_make and line 13:

          from catkin.builder import apply_platform_specific_defaults  # noqa: E402

What fixed the Issue for me was to do:

source /opt/ros/$ROS_DISTRO/setup.bash

before catkin_make

I had the same issue. The first catkin_make command in a clean catkin workspace must be:

$ catkin_make -DPYTHON_EXECUTABLE=/usr/bin/python3

Only if you are using ROS Melodic (or any other non-Python 3 version of ROS) and are trying to force Catkin to use Python 3.
