Raspberry Pi - GPIO in Python

Question

I am trying to get my Raspberry Pi's GPIO pins working, and I am following Tutorial: How to use your Raspberry Pi like an Arduino.

( I'm working through SSH running Raspbian.) I have successfully installed distribute.

When trying to install PIP, I get the error shown below.

How can I fix it?

It's because curl was sudoed instead of python. You must do:

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

Or if you prefer, download the file and then run it:

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