Raspberry Pi - Python中的GPIO

Question

我试图让我的Raspberry Pi的GPIO引脚工作,我正在遵循教程:如何像Arduino一样使用你的Raspberry Pi.

(我正在通过运行Raspbian的SSH工作.)我已经成功安装了分发版.

在尝试安装PIP时,我收到如下所示的错误.

我该如何解决？

这是因为curl被sudo编代替python.你必须这样做:

$ curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | sudo python

或者如果您愿意,请下载该文件然后运行它:

$ curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
$ sudo python get-pip.py
