译：

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:

dist-packages 是 Debian特定惯例，这也存在于像是ubuntu上。如果使用Debian软件管理器安装，模块将被安装到 dist-packages：

/usr/lib/python2.7/dist-packages

Since easy_install and pip are installed from the package manager, they also use dist-packages, but they put packages here:

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

From the Debian Python Wiki:

从 Debian Python Wiki:

dist-packages instead of site-packages. Third party Python software installed from Debian packages goes into dist-packages, not site-packages. This is to reduce conflict between the system Python, and any from-source Python build you might install manually.

dist-packages取代了site-packages。从Debian安装包安装的第三方的Python软件被安装到 dist-packages,不是 site-packages.这是为了减少，系统自带python 和你手动安装的python 之间的冲突。

This means that if you manually install Python from source, it uses the site-packages directory. This allows you to keep the two installations separate, especially since Debian and Ubuntu rely on the system version of Python for many system utilities.

这就是说，如果你手动安装python，它会直接使用目录site-packages。这允许你让两个安装隔离开来，特别是因为Debian 和 Ubuntu 应用 python的系统版本到许多的系统实体。

>>> from distutils.sysconfig import get_python_lib
>>> print(get_python_lib())
