Python包管理工具介绍
本文介绍了Python的包管理工具，强调了egg的基本结构及其相似于Java的jar包。探讨了使用pip和virtualenv进行依赖管理的问题，并引入了buildout作为构建环境的解决方案。还提到了私人PyPI的使用以避免重复下载安装。

Python包管理工具介绍
- 1. python包管理工具介绍 杨昆y@zhihu.com
- 2. 进入python的世界 Python如何管理它的软件？ egg是python组件的基本单位， 类似java中的jar包，ruby中 的gem。 easy_install/pip 即是python的 apt-get。 $easy_install xxx $pip install xxx
- 3. egg的结构 $ tree hello hello ├──hello │ └── __init__.py ├── hello.egg-info │ ├── PKG-INFO │ ├── SOURCES.txt │ ├── dependency_links.txt │ ├── entry_points.txt │ ├── not-zip-safe │ └── top_level.txt ├── setup.cfg └── setup.py
- 4. 包的依赖关系 $ cat setup.py fromsetuptools import setup, find_packages setup(name='hello', version=version, ... keywords='', author='', install_requires=[ 'tornado', 'mysql-python', 'cherrypy', ], ... )
- 5. 用namespace来组织你的包 setup.py ~~~~~~~~~~~ $ tree fly.skels setup( ... fly.skels/ namespace_packages=['fly'], ├── README.rst ├── fly ) │ ├── __init__.py │ └── skels │ └── __init__.py ├── fly.skels.egg-info ├── setup.cfg └── setup.py
- 6. 使用virtualenv和pip (sandbox) $ pipinstall -r requirements.txt (sandbox) $ cat requirements.txt simplejson redis==2.0.0 -e svn+http://svn.myproject.org/svn/MyProject/trunk#egg=MyProject -e git://git.myproject.org/MyProject.git#egg=MyProject tornado sqlalchemy
- 7. virtualenvwrapper ● 创建虚拟环境 $ mkvirtualenv testenv ● 在多个虚拟环境之间切换 $ lsvirtualenv sandbox testenv $ workon sandbox (sandbox)$
- 8. virtualenv的问题 ● 多版本软件管理混乱 ● pip安装可能会失败，easy_install不够灵活 ● 重复下载，安装，在多项目及有c包的时候耗时较长 ● 还是需要手动构建环境
- 9. 认识buildout ● 从一个配置文件，可以构建整个环境, wirteonce, deploy often。 类似于java中的maven ● python包版本控制 ● 利用系统中已有的软件，无需重复下载安装 ● 各种recipe用于支持开发、部署等
- 10. 运行buildout $ python bootstrap.py $./bin/buildout
- 11. pin versions [buildout] versions =versions [versions] tornado = 2.3 sqlalchemy = 0.7.8 hiredis = 0.1.1 flask = 0.9
