[bug\_fix] ModuleNotFoundError: No module named 'distutils'

Install \`setuptools\` which now includes distutils \(or use \`pip install setuptools\`\). Alternatively, for Python 3.12\+, use \`pip install setuptools\` or \`pip install --upgrade setuptools\`. If you are building a package, modify \`setup.py\` to import from \`setuptools\` instead of \`distutils\`.

Journey Context:
A developer upgraded to Python 3.12 and tried to run an old project that used \`from distutils.core import setup\`. The error \`ModuleNotFoundError: No module named 'distutils'\` appeared. The root cause: Python 3.12 removed the \`distutils\` module from the standard library \(PEP 632\). The fix was to install \`setuptools\`, which provides the \`distutils\` module as a compatibility layer. The developer ran \`pip install setuptools\` and the import worked. For modern projects, they should replace \`distutils\` imports with \`setuptools\` equivalents. This error is common when upgrading Python or using legacy packages.
