pypiFrom setup.py to pyproject.toml: A Practical Migration Guide with Poetry
Python projects still use fragile setup.py files. Switching to pyproject.toml centralizes metadata, separates packaging from runtime, and unlocks modern build backends like Poetry. This blog walks through the why, how, and trade‑offs with a concrete example and actionable next steps.
poetryChoosing a PyPI Build Backend: Setuptools, Poetry, or Flit – A Decision Guide
Decide between setuptools, Poetry, or Flit for your PyPI package by comparing legacy support, lock‑file availability, and binary extension handling. Follow a step‑by‑step validation to build, upload, and install a test wheel, ensuring your chosen backend works with your CI and deployment workflow.
pythonDistutils compatibility boundary in Python 3.12 deployment builds
Python 3.12 removed the long-deprecated distutils package from the standard library, shifting any deployment or build script that imports distutils directly onto a replacement. Setuptools provides a vendored distutils through its _distutils_hack, but that shim activates only when setuptools is imported first. The result is an unresolved compatibility boundar
How to install a package using pip in editable mode with pyproject.toml?
When a project is specified only via pyproject.toml (i.e. no setup.{py,cfg} files), how can it be installed in editable mode via pip (i.e. python -m pip install -e . )? I tried both setuptools and poetry for the build system, but neither worked: [build-system] requires = ["setuptools", "wheel"] build-backend = "setuptools.build_meta" [build-system] requires
How to reference a requirements.txt in the pyproject.toml of a setuptools project?
I'm trying to migrate a setuptools -based project from the legacy setup.py towards modern pyproject.toml configuration. At the same time I want to keep well established workflows based on pip-compile , i.e., a requirements.in that gets compiled to a requirements.txt (for end-user / non-library projects of course). This has important benefits as a result of t
