Question

我有一个python脚本，我试图在启动时使用

运行

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

使用以下命令

#!/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")

脚本ShutdownJumper.py以：

开头

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

当我重启我的RPi时，我收到了以下电子邮件：

echo "hello"

我尝试过更改PATH in the crontab，所以无济于事。

Answer 1

尝试在crontab上使用此代码

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

crontab没有为Rpi.GPIO运行python脚本
