如何打包python模块依赖的共享对象? [英] How to package shared objects that python modules depend on?

问题描述

我有一个使用C ++实现的python软件包，我正在使用setuptools分发该软件包.我的C ++代码取决于某些共享库，特别是boost.python库.我应该如何分发这些共享对象?目前，我要求软件包用户单独安装boost C ++库，但我宁愿将所有内容捆绑在一个setuptools发行版中，以使他/她更轻松.目前，除了安装我的软件包之外，他们还必须设置Boost库及其 LD_LIBRARY_PATH 环境变量.

I have a python package implemented in C++ that I am distributing using setuptools. My C++ code depends on some shared objects, specifically the boost.python library. How should I distribute these shared objects? At the moment I ask the package user to install the boost C++ libraries separately but I would rather bundle everything in one setuptools distribution to make it easier for him/her. At the moment they must set up the boost libraries and their LD_LIBRARY_PATH environment variable in addition to installing my package.

推荐答案

声明依赖项

setup.py 中有一个名为 install_requires = ["] 的选项:例如:

Declaring dependencies

There is an option in setup.py called install_requires = [""] : Ex :

setup(
    name='django-cherrypy',
    version='0.1',
    packages=packages,
    license='LICENSE',
    description='cherrypy, running under django',
    long_description=open('README.md').read(),
    author='Calvin Cheng',
    author_email='[e-mail]',
    install_requires=['cherrypy-wsgiserver'],
    extra_requires=['newrelic'],
    url='https://github.com/od-eon/django-cherrypy',
)

此设置要求使用chrerryPy WSGI服务器库.

This setup ask for chrerryPy WSGI server library.

PiPy中的缺陷:

Depedencies in PiPy :

1. 在安装项目时，通过使用EasyInstall，setup.py安装或setup.py开发，并非所有依赖项已安装的文件将通过PyPI定位，下载，构建(如果必要)，然后安装.
2. 项目中的任何脚本都将是装有包装的包装盒，可验证包装盒的可用性在运行时指定依赖项，并确保正确版本会添加到sys.path中(例如，如果已经有多个版本已安装).
3. Python Egg发行版将包含元数据文件列出依赖项

PyPI中没有的依赖项

Dependencies that aren’t in PyPI

如果您的项目依赖于未在PyPI中注册的软件包，只要它们可用，您仍然可以依靠它们下载为:

If your project depends on packages that aren’t registered in PyPI, you may still be able to depend on them, as long as they are available for download as:

• 标准distutils sdist格式的鸡蛋，
• 单个.py文件，
• 或VCS存储库(Subversion，Mercurial或Git).您只需要向setup()的dependency_links参数添加一些URL.
