I have the same on Void Linux; turns out tput is part of the ncurses package, and installing that should fix it (on any Linux flavour).

I also created a PR which should fix it: #423

I try #423, not worked also

I cancel tput, return the result directly 😂

def get_size():
    # TODO maybe use os.get_terminal_size ?
    # return (
    #     int(subprocess.check_output(['tput', 'cols'])),
    #     int(subprocess.check_output(['tput', 'lines']))
    # )
    
    return (200, 50)
