Hi guys !!! I've recently started to try install rosserial from http://wiki.ros.org/rosserial_arduino... after rosserial was installed i tried to build in catkin_ws but i get some error like that :

[  0%] Built target std_msgs_generate_messages_eus

make[2]: *** No rule to make target '/usr/lib/libpython3.7m.so', needed by '/home/krsbi/catkin_ws/devel/lib/librosserial_server_lookup.so'.  Stop.

fatal: destination path 'rosserial' already exists and is not an empty directory.

I would be very glad if someone could help me :)
