Python-ImportError：没有名为伺服的模块

Question

I'm using Raspberry PI for my robotic project. I got this error when try run this code into my raspberry PI through terminal.

#servo_example.py
import servo
servo.servo_setup()
#0 - 180 degrees only!
servo.servo_set_deg(145)
servo.servo_cleanup()

Error message

Traceback (most recent call last):
  File "servo_example.py", line 2, in <module>
    import servo
ImportError: No module named servo

Why I got this error message? How I can fix it?

Answer 1

You have named your script servo.py . This means that when you import servo , you are importing your own script. It doesn't have a function named servo_setup so you get an error. You can't import the system's servo.py while your own script is named servo.py . Solution: name your script something else.
