Resolve deprecation warnings thrown when installing in editable mode

kurtmckee · kurtmckee · commit 406c65b8ae06 · 2026-01-06T15:50:23.000-06:00
Running `pip install -e.` displays the following deprecation warnings: ``` DEPRECATION: Legacy editable install of python-slugify==8.0.4 from file:///.../pr-python-slugify (setup.py develop) is deprecated. pip 25.3 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64. If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. Please consult the setuptools documentation for more information. Discussion can be found at pypa/pip#11457 ```
