Cloudlift is Breaking in Python 3.12

[tasnimzotder]

Issue Description

Cloudlift fails to run on Python 3.12 due to dependency issues related to the removed distutils module. The error manifests in two ways:

1. Initially fails with six.moves import error.
2. After removing six dependency, fails with missing distutils module error.

Root Cause

• distutils was deprecated in Python 3.10 and removed in Python 3.12. See: https://docs.python.org/3.12/library/distutils.html#module-distutils.
• Cloudlift uses LooseVersion from distutils in cloudlift/config/environment_configuration.py (line 6)

Steps to Reproduce

1. Create a Python 3.12 virtual environment
2. Run pip install .
3. Execute cloudlift --version

Now if we remove six==1.10.0 from the dependencies, and then reinstall and run cloudlift version check, we get:

Solution

Add setuptools as a dependency, which provides the removed distutils functionality. With updated requirements.txt:

boto3==1.34.111  
awscli==1.32.111
