本地打包，setup安装

一、distutils

使用：distutils 进行打包，步骤如下，以单一文件为例。

1、创建文件

在同一目录下。写一个foo.py文件：

#-*- coding:utf-8 -*-
def sum(*values):
    s = 0
    for v in values:
        i = int(v)
        s = s + i
    print s

def output():
    print ‘print something‘

写一个setup.py文件：

#-*- coding:utf-8 -*-
from distutils.core import setup
setup(name=‘foo‘,
    version=‘1.0‘,
    py_modules=[‘foo‘],
)

2、创建源码包

运行python setup.py sdist可以为模块创建一个源码包，在当前目录下，创建dist目录。

dist里面有个文件名为foo-1.0.tar.gz，这个就是可以分发的包。使用者拿到这个包后，解压。

3、安装脚本

可以在源码包foo-1.0目录下执行：python setup.py install --record log。

也可以直接在最开始的setup.py处，执行：python setup.py install --record log。

foo.py就会被拷贝到python类路径下，可以被导入使用。

使用--record log：会把安装的信息记录在log下，然后在要卸载的时候，使用cat log | xargs rm －rf 就可以卸载。

二、setuptools

以模块（一个文件夹下多个py文件）为例。

1、创建文件

创建文件目录：

/example_pkg
  /example_pkg
    __init__.py
  setup.py
  LICENSE
  README.md

setup.py文件：

# -*- coding:utf-8 -*-
import setuptools
with open("README.md", "r") as fh:
    long_description = fh.read()
setuptools.setup(
    name="foo",
    version="0.0.1",
    author="Example Author",
    author_email="author@example.com",
    description="A small example package",
    long_description=long_description,
    long_description_content_type="text/markdown",
    url="https://github.com/pypa/sampleproject",
    packages=setuptools.find_packages(),   # 指定需要安装的模块
    # packages=find_packages(exclude=[‘contrib‘, ‘docs‘, ‘tests*‘]),
    # py_modules=["six"], # 剔除不属于包的单文件Python模块
    # install_requires=[‘peppercorn‘], # 指定项目最低限度需要运行的依赖项
    # python_requires=‘>=2.6, !=3.0.*, !=3.1.*, !=3.2.*, <4‘, # python的依赖关系
    # package_data=
    # ‘sample‘: [‘package_data.dat‘],
    # , # 包数据，通常是与软件包实现密切相关的数据
    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 :: 2.6‘,
        ‘Programming Language :: Python :: 2.7‘,
        # ‘Programming Language :: Python :: 3‘,
        # ‘Programming Language :: Python :: 3.2‘,
        # ‘Programming Language :: Python :: 3.3‘,
        # ‘Programming Language :: Python :: 3.4‘,
        "Operating System :: OS Independent",
    ],
)

name：包的名字

version：版本号

author，author_email：作者信息

description：是一个简短的，一句话的包的总结

long_description：是包的详细说明。这显示在Python Package Index的包详细信息包中。在这种情况下，加载长描述README.md是一种常见模式

long_description_content_type：索引什么类型的标记用于长描述。在这种情况下，它是Markdown

url：项目主页的URL

packages：自动发现所有包和子包，而不是手动列出每个包。在这种情况下，包列表将是example_pkg，因为它是唯一存在的包。

创建README.md：

# Example Package
This is a simple example package. You can use
[Github-flavored Markdown](https://guides.github.com/features/mastering-markdown/)
to write your content.

创建LICENSE：

上传到Python Package Index的每个包都包含许可证，这一点很重要。这告诉用户安装您的软件包可以使用您的软件包的条款。有关选择许可证的帮助，请参阅 https://choosealicense.com/。选择许可证后，打开 LICENSE并输入许可证文本。例如，如果您选择了MIT许可证：

2、安装脚本

安装：python setup.py install --record log。

卸载：cat log | xargs rm －rf
