Python，virtualenv，需要distpackages来运行scrip

Question

Python、virtualenv和linux-noob全部3个。在

我有一个小python项目，它使用/usr/local/lib/python2.7/dist-packages中的下载包（PyFPDF）。一切都很好。在

我已经读过，使用virtualenv是一种更好的方法，因为它可以使项目和依赖于项目的包彼此分离，并与主python系统分离。在

因此，在建立了virtualenv之后，我现在有了：

~/python/project/folder
                 |_py script file
                 |_folder with some project related files
                 |_env folder

一。在

然而，当我运行脚本时，我收到了一条关于缺少PIL的消息。在

我看到PIL实际上位于原始python设置中。 /usr/lib/python2.7/dist-packages/

我的env设置根本没有dist packages文件夹-链接或其他我认为是重点，即env使用通用的系统范围的python包，但也允许您使用特定于项目的包。在

我对我最初的设置如何工作更加困惑，因为如上所述，我运行的是/usr/local/lib/python2.7/dist-packages/，它没有PIL。在

很明显，我不明白这两者之间的细微差别：

/usr/local/lib/python2.7/dist-packages/（无PIL）和

/usr/lib/python2.7/dist-packages/（有PIL）

总之，长短不一的是，为了让我的项目在env中运行，我在/pythonproject/env/lib/python2.7/中创建了一个shortcut，它链接到{}

这个脚本现在运行得很好，但我不能不觉得我已经侵入了它，我没有使用virtualenv真正的精神。在

我希望我的描述比泥巴稍微清楚一点。就像我说的，我在这三条战线上是个无名小卒，但我要试试看。希望有人能帮忙。在
