python中setuptools是什么
Setuptools是Python Distutils的加强版,可以让程序员更方便的创建和发布 Python 包,特别是那些对其它包具有依赖性的状况。用setuptools构建和发布的包与用Distutils发布的包是类似的。
包的使用者无需安装setuptools就可以使用该包。如果用户是从源码包开始构建,并且没有安装过setuptools的话,则只要在你的setup脚本中包含一个bootstrap模块(ez_setup),用户构建时就会自动下载并安装setuptools了。
一:基本用例
下面是一个使用setuptools的简单例子:
from setuptools import setup, find_packagessetup(
name = "HelloWorld",
version = "0.1",
packages = find_packages(),
)
上面就是一个最简单的setup脚本,使用该脚本,就可以产生eggs,上传PyPI,自动包含setup.py所在目录中的所有包等。
当然,上面的脚本过于简单,下面是一个稍微复杂的例子:
from setuptools import setup, find_packagessetup(
name = "HelloWorld",
version = "0.1",
packages = find_packages(),
scripts = ['say_hello.py'],
# Project uses reStructuredText, so ensure that the docutils get
# installed or upgraded on the target machine
install_requires = ['docutils>=0.3'],
package_data = {
# If any package contains *.txt or *.rst files, include them:
'': ['*.txt', '*.rst'],
# And include any *.msg files found in the 'hello' package, too:
'hello': ['*.msg'],
},
# metadata for upload to PyPI
author = "Me",
author_email = "me@example.com",
description = "This is an Example Package",
license = "PSF",
keywords = "hello world example examples",
url = "http://example.com/HelloWorld/", # project home page, if any
# could also include long_description, download_url, classifiers, etc.
)
