python编译错误，无法导入名称“gpio”

Question

我在这里尝试这个教程： http://www.instructables.com/id/Orange-Pi-One-Python-GPIO-basic/?ALLSTEPS

每当我执行.py文件时，都会出现错误“cannot import name'gpio'”

以下是我在安装完其他所有东西后使用的代码，在tut中声明：

#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，所以请容忍我。 非常感谢你。在

橙色圆周率也有同样的问题。。。我从https://pypi.python.org/pypi/pyA10Lime获得了python库，然后它就工作了：
