Hi, --8<---------------cut here---------------start------------->8--- + (build-system pyproject-build-system) + ;; Tests require pyautogui which is not packaged yet. + (arguments + (list + #:tests? #f)) --8<---------------cut here---------------end--------------->8--- Did you try to keep some portion of tests or they all depend on pyautogui? https://github.com/vlachoudis/bCNC/tree/master/tests I've checked pyautogui, we may keep it for the next iteration for now, more than a half missing dependencies. https://github.com/asweigart/pyautogui/blob/master/setup.py + python3-Xlib + pymsgbox - pytweening - pyscreeze - pygetwindow - mouseinfo --- Oleg
