Python 打包与分发：setuptools 和 pyproject.toml

传统 setup.py

from setuptools import setup, find_packages



setup(

    name="my-package",

    version="0.1.0",

    packages=find_packages(),

    install_requires=[

        "requests>=2.25.0",

        "numpy"

    ],

    entry_points={

        "console_scripts": [

            "mycli = mypackage.cli:main",

        ]

    },

    author="Your Name",

    description="A sample package",

)

现代 pyproject.toml (PEP 621)

[build-system]

requires = ["setuptools>=61.0"]

build-backend = "setuptools.build_meta"



[project]

name = "my-package"

version = "0.1.0"

description = "A sample package"

authors = [{name = "Your Name", email = "you@example.com"}]

dependencies = [

    "requests>=2.25.0",

    "numpy"

]



[project.scripts]

mycli = "mypackage.cli:main"

构建与发布

# 安装构建工具

pip install build twine



# 构建分发包

python -m build



# 上传到 PyPI

twine upload dist/*

本地安装

pip install -e .  # 开发模式安装（可编辑）

规范的打包流程能让你的代码被更多人方便地使用。
