词汇
- setup.py
- 使用代码来描述发布(distribution)
- 区别于包,一个 distribution 可以包含 0 或多个包,但一般都是保持 1-1-1 关系:1 个发布,1 个包,1 个名字
- 一般以引入 setuptools 和 distutils 开始
__init__.py
- py2 认为包含这文件的就是包/模块
__main__.py
- 入口
- distutils
- 内建模块,不推荐使用,很久未维护
- setuptools
- 非内建模块,但一般虚拟环境都有
- 最小化代码
import setuptools
setuptools.setup(
name='my_special_package',
packages=setuptools.find_packages(),
)
- tox
- 管理虚拟环境
- 主要用于测试和构建
- DevPI
- PyPI 兼容的本地开发服务
pip install devpi-server
devpi-server --start --init
# 指定用户、安装包
pip install devpi-client twine
devpi use http://localhost:3141
devpi user -c testuser password=123
devpi login testuser --password=123
devpi index -c dev bases=root/pypi
devpi use testuser/dev
twine upload --repository http://localhost:3141/testuser/dev \
-u testuser -p 123 my-package-18.6.0.tar.gz
pip install -i http://localhost:3141/testuser/dev my-package
- pex
- Python 转可执行文件
- shiv
- 类似于 pex,但更简单,直接使用 pip
- xar - eXecutable ARchive
- 设计于打包自包含可的可执文件,以 py 为主
python setup.py bdist_xar --console-scripts=my-script
entry_points=dict(
console_scripts=["my-script = package.module:function"],
)
- pyproject.toml
- poetry
- flit
