import shapely.geometry抛出AttributeError：function＆＃39; GEOSversion＆＃39;未找到

Question

import shapely.geometry在解释器中工作正常，但代码在运行时抛出此错误：

AttributeError: function 'GEOSversion' not found

也试过

import geos  
ImportError: No module named geos`

但是Shapely曾经完美地运行过。

在SO中没有找到关于此问题的任何帖子。任何帮助深表感谢。谢谢！

从this link supposed to include GEOS dependencies安装的Shapely-1.3.2.win-amd64-py2.7.exe。

在Win7 64bit上的Python 2.7 64位Anaconda。将Eclipse与PyDev一起使用
