正在解决的基本问题是依赖项和版本之一，以及间接权限.想象你有一个需要版本的应用程序1 LibFoo，但另一个应用程序需要版本 2. 你如何使用这两个应用程序?如果你将所有东西安装到/usr/lib/python2.4/site-packages(或无论您的平台标准如何位置是)，很容易在一个你无意中的情况升级不应升级的应用程序升级.

The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.4/site-packages (or whatever your platform's standard location is), it's easy to end up in a situation where you unintentionally upgrade an application that shouldn't be upgraded.

或者更一般地说，如果你想怎么办安装应用程序并离开它是?如果应用程序有效，任何更改其库或这些库的版本可能会损坏应用程序.

Or more generally, what if you want to install an application and leave it be? If an application works, any change in its libraries or the versions of those libraries can break the application.

另外，如果你不能安装怎么办打包成全局站点包目录?例如，在共享主持人.

Also, what if you can't install packages into the global site-packages directory? For instance, on a shared host.
