This is the script I am running to connect to a drone with px4 autopilot with a USB cable in com4.

from dronekit import connect

vehicle = connect(‘com4’, wait\_ready=True)  
print(“connection command run”)

This is the error it continually throws:

Traceback (most recent call last):  
File “C:/Users/ethan/project/DroneKit Test.py”, line 6, in   
vehicle = connect(‘com4’, wait\_ready=True)  
File “C:\Python27\lib\site-packages\dronekit\__init_\_.py”, line 3159, in connect  
handler = MAVConnection(ip, baud=baud, source\_system=source\_system, source\_component=source\_component, use\_native=use\_native)

import serial  
ImportError: No module named serial

I would really appreciate your help with this. I have been stuck at trying to connect to my drone for over a month. Also, if you have an alternative to dronekit that could you point me in the right direction and maybe include sample code to connect to the drone? Thank you!
