In my catkin_workspace a python module was not able to use another python module. Advice on the internet was to delete the "devel" and "build" folder in the workspace and try to build again.

After i did thati get the following error (additionally i also get this error when i create a new workspace):

em: error: unrecognized arguments: --raw-errors -F -o /home/tim-htk/robotik/catkin_ws_new/build/catkin_generated/order_packages.cmake /opt/ros/noetic/share/catkin/cmake/em/order_packages.cmake.em
