使用时出现错误gpio.setup(pin, GPIO.OUT)

我目前正在使用 Ubuntu Mate For Raspberry Pi 2 并使用带有python-rpi.gpio 0.5.10.1模块的 Python 2.7。

SegmentationFault当我尝试输入时它会抛出GPIO.setup(pin, GPIO.OUT)。

编辑：这是我一直在处理的代码

GPIO.cleanup()

我不知道这个问题，我认为它与 python-rpi.gpio 模块相关，因为我对 Raspbian 没有任何问题，预安装了 python-rpi.gpio。

我有同样的症状，带有 Ubuntu Mate 的 Raspberry Pi 2，0.5.11 模块。我的代码要简单得多：

import time
import RPi.GPIO as GPIO
print "before GPIO.setmode"
GPIO.setmode(GPIO.BOARD)
print "before GPIO.setup"
GPIO.setup(11, GPIO.IN)
print "after GPIO.setup"

它在 GPIO.setup 期间出现段错误。我会尝试切换回 Raspbian，看看是否可行。如果是这样，也许从那里卸载并重新安装 RPi.GPIO。
