Hi Chris,

`pip` may be assigned to the wrong version of python. I can see there are some similar errors in the forum thread for that guide:

> Hi @Bryce From the readme for the git repository currently used by the tutorial: This Python code is being phased out and replaced with [https://github.com/rpi-ws281x/rpi-ws281x-python](https://github.com/rpi-ws281x/rpi-ws281x-python) If you’re just looking to install the Python library, you can: sudo pip install rpi\_ws281x or sudo pip3 install rpi\_ws281x depending on your Python version of choice or find releases here: [https://github.com/rpi-ws281x/rpi-ws281x-python/releases](https://github.com/rpi-ws281x/rpi-ws281x-python/releases) So please update the tutorial to install the module with pip/pip3 …

We’ll have to have a bit of a dig and see what the root cause is, though I suspect it’s mostly just an issue with python versions.
