make: Nothing to be done for 'import'.

Above is the error massage.I tried to do this for generate_traffic API, but I met a problem that world.get_random_location_from_navigation() function cannot get the info of navigation. I figured out the reason may cause this problem is my own map doesnt have .bin file in the nav, and Im trying to generate one for my customized map. If anyone know how to generte this .bin file or any other method can allow my navigation info to be correctly load by py api please lend me hand, thanks!
