在 python 2.7 64 位上安装 cartopy 时出现 GEOSversion 错误

Question

我从http://www.lfd.uci.edu/~gohlke/pythonlibs/下载了cartopy的.whl文件。使用命令行pip install cartopyETC.whl，提示安装成功。但是当我使用 import cartopy 测试它时，出现以下错误：

Answer 1

我更深入（和更长）地挖掘，并找到了这个页面。我卸载了 shapely（pip install shapely），而是从 http://www.lfd.uci.edu/~gohlke/pythonlibs/ pip 安装 shapely 的 .whl 文件。当我安装Cartopy的.whl文件后，好像问题解决了
