参考如下：

“OSError: [WinError 126] 找不到指定的模块”的解决办法_我是一个对称矩阵的博客-CSDN博客_oserror 找不到指定模块 1. 问题分析出现找不到指定模块的问题通常是程序要加载某个DLL文件，但是这个DLL文件不存在就报错了。从这一句可以看出，程序试图加载一个’geos_c.dll’，os.path.join(sys.prefix, ‘Library’, ‘bin’, ‘geos_c.dll’)组成了这个DLL文件的完整绝对路径，那么我们只需要找到这个绝对路径，并去网上下载这个DLL文件放入这个绝对路径即可。2. 找到绝对路径我们打印出这个路径：于是我们得到了这个完整的绝对路径3. 下载所需的DLL文件程序 https://blog.csdn.net/qq_40243750/article/details/120123119
