Packaging a Python project with pyproject.toml
이 문서는 아직 한국어로 제공되지 않습니다. 원문을 표시합니다.
pyproject.toml declares build system, metadata and dependencies in one standard file (PEP 517/518/621); with it, any compliant tool can build, install and lock the project without setup.py.
Goal
Make the project installable and buildable with standard tools from a single declarative file, so that contributors and pipelines do not depend on a particular workflow tool.
Prerequisites
A package layout (src/yourpackage/ recommended) and a chosen build backend (setuptools, hatchling, flit-core or similar).
Steps
- Add a
[build-system]table naming the backend and its version requirement. - Add a
[project]table withname,version(ordynamic = ["version"]),description,readme,requires-python,license,dependenciesandoptional-dependenciesfor extras such astestordocs. - Declare entry points (
[project.scripts]) instead of shipping ad hoc launcher scripts. - Put tool configuration (
[tool.ruff],[tool.mypy],[tool.pytest.ini_options]) into the same file to keep the repository root tidy. - Build with
python -m buildand install into a fresh virtual environment to verify that the built distribution contains everything the code imports. - Pin the full dependency tree for applications in a lockfile; keep library dependencies as ranges.
Expected result
pip install . and pip install -e . work; the built wheel installs cleanly elsewhere; metadata appears correctly on the package index.
Limits and test basis
Application lockfiles are not standardised across tools; choose one and document it. Data files need explicit inclusion rules per backend. The structure follows the cited guide and PEP 621.
