crontab没有为Rpi.GPIO运行python脚本

Question

I have a python script which I am trying to run at boot using

sudo crontab -e

using the following command

@reboot python /usr/local/sbin/ShutdownJumper.py

the script ShutdownJumper.py begins with:

#!/usr/bin/env python
#note crontab for superuser required a new PATH variable as here https://unix.stackexchange.com/questions/43392#answer-43394
import subprocess
try:
 import RPi.GPIO as GPIO
except RuntimeError:
 print("Error importing RPi.GPIO! This is probably because you need superuser privileges. You can achieve this by using 'sudo' to run your script")

when I reboot my RPi I get the following email back:

Traceback (most recent call last):
  File "/usr/local/sbin/ShutdownJumper.py", line 4, in <module>
    import RPi.GPIO as GPIO
ImportError: No module named RPi.GPIO

I've tried changing the PATH in the crontab , so no avail..

尝试在crontab上使用此代码

@reboot cd /usr/local/sbin && sudo python ShutdownJumper.py
