python - 编译错误 - 无法导入名称 'gpio'

Question

我在这里试用本教程: http://www.instructables.com/id/Orange-Pi-One-Python-GPIO-basic/?ALLSTEPS

每当我执行我的 .py 文件时，我都会收到错误“无法导入名称‘gpio’”

这是我在安装所有其他东西后使用的代码，在图文中说明:

#import the library
from pyA20.gpio import gpio
from pyA20.gpio import port
from time import sleep

#initialize the gpio module
gpio.init()

#setup the port (same as raspberry pi's gpio.setup() function)
gpio.setcfg(port.PA7, gpio.OUTPUT)

#now we do something (light up the LED)
gpio.output(port.PA7, gpio.HIGH)

#turn off the LED after 2 seconds
sleep(2)
gpio.output(port.PA7, gpio.LOW)

我对这一切都很陌生，所以请多多包涵。非常感谢。

在 orange pi Zero 上遇到了同样的问题...我从 https://pypi.python.org/pypi/pyA10Lime 得到了 python 库然后它起作用了:
