Overview Description

As I was working through the getting started tutorial and tried to run this code coala --files=src/\*.c --bears=SpaceConsistencyBear --save, I got the following output:

An unknown error occurred. This is a bug. We are sorry for the inconvenience. Please contact the developers for assistance. During execution of coala an exception was raised. This should never happen. When asked for, the following information may help investigating:
[INFO][10:49:06] Exception was:

ImportError: cannot import name 'Iterable' from 'collections' (/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/collections/__init__.py)

After reading about a similar issue in the past, I ran pip install 'setuptools==17.0' but that still didn't resolve the issue.

Steps to Reproduce

1. git clone https://github.com/coala/coala-tutorial
2. cd coala-tutorial
3. coala --files=src/*.c --bears=SpaceConsistencyBear --save
4. pip install 'setuptools==17.0'

Expected Results
