Python setuptools简介

distutils(包分发的始祖) 简介

distutils 是 Python 的一个标准库，从命名上很容易看出它是一个分发（distribute）工具（utlis），它是 Python 官方开发的一个分发打包工具，所有后续的打包工具，全部都是基于它进行开发的

distutils 的精髓在于编写 setup.py，它是模块分发与安装的指导文件

setuptools 简介

setuptools 是 distutils 增强版，不包括在标准库中。其扩展了很多功能，能够帮助开发者更好的创建和分发 Python 包。大部分 Python 用户都会使用更先进的 setuptools 模块。

build

构建安装时所需的所有内容：

python setup.py build

install

安装包到系统环境中。该命令会将当前项目安装到当前Python环境的”site-packages”目录下，这样其他项目就可以像导入标准库一样导入该项目的代码了

python setup.py install

develop

以开发方式安装包。

如果项目在开发过程中会频繁变更，每次安装还需要先将原来的版本卸掉，会很麻烦。使用”develop”开发方式安装的话，项目代码不会真的被拷贝到本地Python环境的”site-packages”目录下，而是在”site-packages”目录里创建一个指向当前项目位置的链接。这样如果当前位置的源码被改动，就会马上反映到”site-packages”里。

python setup.py develop

register、upload

用于包的上传发布

python setup.py register
# 发布源码包
python setup.py sdist upload

sdist

构建源码分发包。该命令会在当前目录下的”dist”目录内创建一个压缩包，默认在 Windows 下为 zip 格式，Linux 下为 tag.gz 格式，也可以通过指定–formats参数指定压缩包格式。

执行 sdist 命令时，默认会被打包的文件：

所有 py_modules 或 packages 指定的源码文件
所有 ext_modules 指定的文件
所有 package_data 或 data_files 指定的文件
所有 scripts 指定的脚本文件

README、README.txt、setup.py 和 setup.cfg文件
该命令构建的包主要用于发布，例如上传到 pypi 上

python setup.py sdist

bdist

构建一个二进制的分发包

python setup.py bdist

bdist_egg

构建一个 egg 分发包，经常用来替代基于 bdist 生成的模式。该命令会在当前目录下的”dist”目录内创建一个”egg”文件，名为”MyApp-1.0-py2.7.egg”。文件名格式就是”项目名-版本号-Python版本.egg”。同时你会注意到，当前目录多了”build”和”MyApp.egg-info”子目录来存放打包的中间结果

python setup.py bdist_egg

bdist_wheel

构建一个 wheel 分发包，egg 包是过时的，whl 包是新的标准。同上面类似，只是打成的包的后缀是.whl

python setup.py bdist_wheel

简单例子

python中安装包的方式有很多种：

源码包：python setup.py install
在线安装：pip install 包名 / easy_install 包名

pip install的东西从哪里来的？

从PyPI （Python Package Index）来的，官网是： https://pypi.python.org/pypi

执行pip install terminaltranslator命令的时候，它就会去从官方网站搜terminaltranslator，搜到了就下载压缩包并解压安装，如果没有搜索到就会报错。

源码包安装

源码包安装就是你在本地编写好了一个模块，自己安装在本地使用，别人(即使是你自己)都不能 pip install xxx 下载你的模块

准备工作

# 1.首先创建我们需要的目录结构和文件(自行创建)
# 当前测试的目录是： /tmp/demo`-- demo|-- helloapp|   |-- hello.py|   `-- __init__.py`-- setup.py# 2.编辑 setup.py
from setuptools import setup, find_packagessetup(name="myhello",version="1.0",author="tsq",author_email="865466036@qq.com",packages=find_packages(),
)# 3.编辑 hello.py
def hello_func():print("HelloWorld")if __name__ == '__main__':hello_func()

打tar包

# 进入setup.py所在的那层目录
cd demo# 检查setup.py 是否有错误(warning不是错误)

请添加图片描述

python使用setuptools打包

特性文件

setup.py、MANIFEST.in、setup.cfg

引入非Python文件

上例中，我们只会将”myhello”包下的源码打包，如果想引入静态文件，如JS、CSS、图片等，怎么做？

答：在项目根目录下添加一个”MANIFEST.in”文件夹。假设我们把所有静态文件都放在”static”子目录下，现在的项目结构如下：

 demo/├ setup.py        # 安装文件├ MANIFEST.in     # 清单文件└ myhello/          # 源代码├ static/     # 静态文件目录├ __init__.py...

我们在清单文件”MANIFEST.in”中，列出想要在包内引入的目录路径：

recursive-include myhello/static *
recursive-include myhello/xxx *

recursive-include表明包含子目录
在”setup.py”中将include_package_data参数设为True：

#coding:utf8
from setuptools import setup
setup(name='MyHello',        # 项目名version='1.0',# 版本号packages=['myhello'],  # 包括在安装包内的Python包include_package_data=True   # 启用清单文件MANIFEST.in
)

如果你想排除一部分文件，可以在”setup.py”中使用exclude_package_date参数：

setup(...include_package_data=True, # 启用清单文件MANIFEST.inexclude_package_date={'':['.gitignore']}
)

依赖管理
我们的项目会依赖其他Python模块，如何在setup.py中管理这些依赖呢？

答：修改”setup.py”文件，加入install_requires参数

#coding:utf8
from setuptools import setup
setup(name='MyHello',        # 项目名version='1.0',# 版本号packages=['myhello'],  # 包括在安装包内的Python包include_package_data=True,   # 启用清单文件MANIFEST.inexclude_package_date={'':['.gitignore']},install_requires=[   # 依赖列表'Flask>=0.10','Flask-SQLAlchemy>=1.5,<=2.1']
)

上面的代码中，我们声明了应用依赖Flask 0.10及以上版本，和Flask-SQLAlchemy 1.5及以上、2.1及以下版本。setuptools会先检查本地有没有符合要求的依赖包，如果没有的话，就会从PyPI中获得一个符合条件的最新的包安装到本地。

可以通过dependency_links指定依赖包下载路径。install_requires中的包在安装时会先去PyPI下载并安装，如果包在PyPI中找不到，则会从dependency_links标识的URL中获取：

setup(...install_requires=[   # 依赖列表'Flask>=0.10','Flask-SQLAlchemy>=1.5,<=2.1'],dependency_links=[   # 依赖包下载路径'http://example.com/dependency.tar.gz']
)

自动搜索Python包

packages=[‘myhello’] ：将Python包”myapp”下的源码打包。

之前我们在”setup.py”中指定了packages=[‘myhello’]，说明将Python包”myhello”下的源码打包。但是如果我们的应用很大，逐一列举需要打包的源码包会很麻烦，这时就需要用到setuptools提供的find_packages()方法来自动搜索可以引入的Python包。

packages=find_packages() ：自动搜索可以引入的Python包，它默认在与 setup.py 文件同一目录下搜索各个含有 init.py 的目录做为要添加的包

#coding:utf8
from setuptools import setup, find_packages
setup(name='MyHello',              # 应用名version='1.0',             # 版本号packages=find_packages(),  # 包括在安装包内的Python包include_package_data=True,  # 启用清单文件MANIFEST.inexclude_package_date={'':['.gitignore']},install_requires=[         # 依赖列表'Flask>=0.10','Flask-SQLAlchemy>=1.5,<=2.1']
)
