python 中 dist-packages 和 site-packages 的区别-优快云博客

site-packages 和 dist-packages 的区别

dist-packages is a Debian-specific convention that is also present in its derivatives, like Ubuntu. Modules are installed to dist-packages when they come from the Debian package manager into this location:/usr/lib/python2.7/dist-packages

dist-packages 是 Debian特定惯例，这也存在于像是ubuntu上（ubuntu 是从 debian衍生来的）。如果使用Debian软件管理器安装，模块将被安装到 dist-packages
查看python库路径:

<code class="language-python hljs  has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-keyword" style="margin: 0px; padding: 0px; color: rgb(0, 0, 136); box-sizing: border-box;">from</span> distutils.sysconfig <span class="hljs-keyword" style="margin: 0px; padding: 0px; color: rgb(0, 0, 136); box-sizing: border-box;">import</span> get_python_lib
print(get_python_lib())</code><ul class="pre-numbering" style="margin: 0px; padding: 6px 0px 40px; box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="margin: 0px; padding: 0px 5px; box-sizing: border-box;">1</li><li style="margin: 0px; padding: 0px 5px; box-sizing: border-box;">2</li></ul>

Since easy_install and pip are installed from the package manager, they also use dist-packages, but they put packages here： /usr/local/lib/python2.7/dist-packages
自从 easy_install 和 pip (注：是python的软件管理其，python有许许多多的软件) 使用，他们也使用 dist-packages,但是路径是：/usr/local/lib/python2.7/dist-packages

根据现实场景：

sudo apt-get install 安装的package存放在 /usr/lib/python2.7/dist-packages目录中
pip 或者 easy_install安装的package存放在/usr/local/lib/python2.7/dist-packages目录
手动从源代码安装的package存放在site-packages目录中

顺带说下包管理工具

Python的包管理工具常见的有easy_install, setuptools, 还有pip, distribute可以看到distribute是setuptools的替代方案，pip是easy_install的替代方案. 而setuptools 和 easy_install 已经越来越不被维护了，所以建议大家试用他们的替代版, 而如果要说 distribute 和 pip 的区别，那么就是pip 的底层实现调用了 distribute 或者 setuptools
