crontab没有为Rpi.GPIO运行python脚本

Question

我有一个python脚本，我正在尝试使用以下命令在启动时运行

sudo crontab -e

使用以下命令

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

脚本ShutdownJumper.py开头为：

#!/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")

重新启动RPi时，我会收到以下电子邮件：

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

我试过更改crontab中的PATH ，所以无济于事。

尝试在crontab上使用此代码

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