一、背景

想让自己写的python库可以使用pip install xxx安装。

二、环境准备

• 注册PYPI账号
• 已经写好的能正常使用的库/方法/项目（可以本地调用）
• 安装依赖库setuptools和twinw

pip install setuptools
pip install twine  # 简化将库发布到PYPI流程的工具
pip install wheel  # 制作whl文件需要

三、步骤

1. 调整目录结构

参考python项目打包结构

|--mypackage__init__.py__version__.py|--common|--config|--src
setup.py
requirements.txt
LICENSE
README.rst
MANIFEST.in
.gitnore

目录文件的作用：

• MANIFEST.in
  当你使用 Python 的打包工具（如 setuptools 或 distutils）创建分发包时，
  它们只会自动包含项目目录中的 Python 模块和包。但是，在某些情况下，你可
  能还需要在分发包中包含一些其他的文件，如文档、配置文件、数据文件等。这
  时，就可以使用 MANIFEST.in 文件来指定要包含的其他文件。

include DrissionPage/configs/configs.ini
include DrissionPage/*.pyi
include DrissionPage/*/*.py
include DrissionPage/*/*.pyi

• setup.py

# -*- coding:utf-8 -*-
from setuptools import setup, find_packageswith open("README.md", "r", encoding='utf-8') as fh:long_description = fh.read()setup(name="DrissionPage",version="3.2.31",author="g1879",author_email="g1879@qq.com",description="Python based web automation tool. It can control the browser and send and receive data packets.",long_description=long_description,long_description_content_type="text/markdown",license="BSD",keywords="DrissionPage",url="https://gitee.com/g1879/DrissionPage",include_package_data=True,packages=find_packages(),zip_safe=False,install_requires=['lxml','requests','cssselect','DownloadKit>=1.0.0','FlowViewer>=0.3.0','websocket-client','click','tldextract'],classifiers=["Programming Language :: Python :: 3.6","Development Status :: 4 - Beta","Topic :: Utilities","License :: OSI Approved :: BSD License",],python_requires='>=3.6',entry_points={'console_scripts': ['dp = DrissionPage.commons.cli:main',],},
)

字段说明：

• version：这个简单，就是包的发布的版本，可以直接写在这，也可以从其他地方引用过来。

• long_description：默认是rst（reStructuredText )格式的，也可以是其他格式，使用long_description_content_type字段指定，这个里面的内容是显示在pypi包首页上。

• packages：申明你的包里面要包含的目录，比如 [‘mypackage’, ‘mypackage_test’] 可以是这种使用我的示例，让setuptools自动决定要包含哪些包

• install_requires：申明依赖包，安装包时pip会自动安装

• LICENSE

• README.md

项目简介,markdown格式

2. 打包上传

项目按照上述结构组织好之后，就可以进行打包了

• check setup.py

python setup.py check

若没问题，无报错信息。

• 生成打包文件

python setup.py bdist_wheel  # 编译生成wheel文件，会产生build,dist,XX.egg-info三个文件夹
pip wheel --wheel-dir=whl文件保存路径 setup.py文件所在路径  # 直接生成whl文件，不产生中间编译结果
python setup.py sdist # 生成tar包，即源码包

• 上传生成的包

python setup.py sdist upload  # 上传source包
python setup.py bdist_wheel upload  # 上传二进制包

• 包的安装

# 源码包安装，解压+编译+安装
python setup.py build
python setup.py install
# whl包
pip install XX.whl

• 测试库是否可以正常安装

python setup.py develop
# 该方法不会真正的安装包，而是在系统环境中创建一个软链接指向包实际所在目录。
# 这边在修改包之后不用再安装就能生效，便于调试
