用Python将库打包发布到pypi代码示例

本篇文章小编给大家分享一下用Python将库打包发布到pypi代码示例，文章代码介绍的很详细，小编觉得挺不错的，现在分享给大家供大家参考，有需要的小伙伴们可以来看看。

1. 注册pypi账号并创建token

首先访问https://pypi.org/ 并注册账号

然后跳转到账号设置

然后选择API token->Add API token

输入token name并在Scope中选择Entire account（第一次需要选择Entire account）

然后在本地，修改.pypirc文件

输入的内容为：

[pypi]
username = __token__
password = {token}

只需要修改{token}为自己的token即可

2. 编写setup.py和setup.cfg

setup.cfg的内容为

[metadata]
license_files = LICENSE.txt

LICENSE.txt是license文件，需要自行编写

setup.py在根目录下，一个示例为

from setuptools import setup
import compileall
from os import path
# 读取readme文件，这样可以直接显示在主页上
this_directory = path.abspath(path.dirname(__file__))
with open(path.join(this_directory, 'README.md'), encoding='utf-8') as f:
    long_description = f.read()

compileall.compile_dir("src")

setup(
    name='my-python',
    version='1.0.2',
    packages=['src',
              'src.main',
              'src.main.config'],
    url='https://github.com/hTangle',
    license='Apache 2.0',
    author='hTangle',
    author_email='',
    description='',
    keywords='',
    python_requires='>=3.4, <4',
    long_description=long_description,
    long_description_content_type='text/markdown',
    install_requires=['requests']
)

具体的字段含义如下：

name: 包名

version: 版本号，支持如下形式

1.2.0.dev1  # Development release
1.2.0a1     # Alpha Release
1.2.0b1     # Beta Release
1.2.0rc1    # Release Candidate
1.2.0       # Final Release
1.2.0.post1 # Post Release
15.10       # Date based release
23          # Serial release

description: 包描述，会放在如下图所示的位置处

url: 包的链接，可以使用github链接，pypi会自动获取到仓库的信息，示例如下：

author: 作者

license: 许可证

classifiers: 分类，示例如下：

classifiers=[
    # How mature is this project? Common values are
    #   3 - Alpha
    #   4 - Beta
    #   5 - Production/Stable
    'Development Status :: 3 - Alpha',

    # Indicate who your project is intended for
    'Intended Audience :: Developers',
    'Topic :: Software Development :: Build Tools',

    # Pick your license as you wish (should match "license" above)
    'License :: OSI Approved :: MIT License',

    # Specify the Python versions you support here. In particular, ensure
    # that you indicate whether you support Python 2, Python 3 or both.
    'Programming Language :: Python :: 2',
    'Programming Language :: Python :: 2.7',
    'Programming Language :: Python :: 3',
    'Programming Language :: Python :: 3.6',
    'Programming Language :: Python :: 3.7',
    'Programming Language :: Python :: 3.8',
    'Programming Language :: Python :: 3.9',
],

keywords: 关键字，和论文的关键字类似

project_urls: 一些项目的其他链接，示例如下

project_urls={
    'Documentation': 'https://packaging.python.org/tutorials/distributing-packages/',
    'Funding': 'https://donate.pypi.org',
    'Say Thanks!': 'http://saythanks.io/to/example',
    'Source': 'https://github.com/pypa/sampleproject/',
    'Tracker': 'https://github.com/pypa/sampleproject/issues',
},

packages: 需要打包的目录，需要以根目录为起点，可以使用

find_packages自动查找包，注意不要漏写

install_requires: 包依赖的其他包

python_requires: python的版本需求

package_data: 需要的额外的文件，例如包强依赖一个本地文件，可以使用如下

package_data={
    'sample': ['package_data.dat'],
},

3. 打包

打包命令为

python setup.py cmd

cmd可以取值为

bdist_wheel : create a wheel distribution

bdist_egg : create an “egg” distribution

sdist : create a source distribution (tarball, zip file, etc.)

bdist : create a built (binary) distribution

bdist_dumb : create a “dumb” built distribution

bdist_rpm : create an RPM distribution

bdist_wininst : create an executable installer for MS Windows

打包为tar.gz

python setup.py sdist

打包好的文件再dist目录下

4. 上传

可以首先使用twine对包进行检查

twine check dist/*

输出如下

再运行上传命令

twine upload dist/*
