Answer 1

错误说明了一切。 The specified module could not be found 表示您没有安装一些必需的包。我猜你错过了 Shapely which is a requirement。下次按照文档中的安装步骤进行操作。或者用conda，更简单

Answer 2

错误可能是由于缺少构建 dll 所需的 C 编译器。解决方法：

从 https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely
pip install Shapely-1.6.4.post2-cp37-cp37m-win_amd64.whl（在 Anaconda 环境下可以使用 conda install）
