Piglow - Error Messages

This sounds like you've got the wrong PiGlow library installed- there are 3 or 4, some of which conflict for the "piglow" name and make a bit of a mess. Our fault for not having a proper library out on day one- but those were early days!

You should first remove all old PiGlow libraries like so:

sudo pip uninstall piglow

And then install our library:

sudo pip install piglow

And hopefully that will solve your woes!
