AttributeError: 'NoneType' object has no attribute 'attrib'

Hey :) I keep getting this error when I try to run Ableton() within venv.

Steps to reproduce:

1. Enter py REPL, either as a part of the system or inside a venv
2. Load pyableton
3. Try to run pyableton to parse an als project (in the current directory)
4. Crash with an error

Try downloading setuptools from inside the venv
