Report #104510

[bug\_fix] ModuleNotFoundError: No module named 'distutils' \(Python 3.12\+\)

Install setuptools explicitly: \`pip install setuptools\`. Alternatively, for legacy packages, add \`setuptools\` to your requirements or use a Python version <3.12.

Journey Context:
Developer upgraded to Python 3.12 and tried to install a package that used \`from distutils.core import setup\`. It failed because distutils was removed in Python 3.12. Root cause: Python 3.12 deprecated and removed distutils; setuptools now provides the same functionality. Fix works by ensuring setuptools is installed, which shims distutils.

environment: macOS 14, Python 3.12, fresh venv, pip install of an older package. · tags: modulenotfounderror distutils python3.12 setuptools deprecation · source: swarm · provenance: Python 3.12 changelog: https://docs.python.org/3/whatsnew/3.12.html\#distutils
