Raspberry Pi - GPIO in Python

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?

You can also make use of the wiringPi library. It's very easy to use.

Here are the links:

For C: https://github.com/WiringPi/WiringPi

For Python: https://github.com/Gadgetoid/WiringPi2-Python

I hope it helps.

I followed the same tutorial but instead of installing pip I just used:

sudo apt-get install rpi.gpio

The rest of the tutorial worked fine with a bit of searching around for some extra info. My whole experience of simple GPIO introduction the subject of my blog post Using Raspberry GPIO Interface which I hope helps too.

Nowadays the Debian packages are named:

python-rpi.gpio - Python GPIO module for Raspberry Pi
python3-rpi.gpio - Python 3 GPIO module for Raspberry Pi

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
