Answer 1

错误更能说明一切。The specified module could not be found表示您没有安装一些必需的软件包。我猜你错过了Shapelywhich is a requirement。下次请遵循文档中的安装步骤。或者使用conda，它更简单。在

Answer 2

错误可能是由于缺少生成dll所需的C编译器造成的。 解决方法：

1. 从https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely安装二进制文件

2. pip安装Shapely-1.6.4.post2-cp37-cp37m-win_amd64.whl（在Python环境中。您可以使用conda安装）
