根据里面的错误提示error: command 'swig.exe' failed: No such file or directory我们需要先安装swig.exe并配置环境变量

如何安装和配置呢，请参考下面的链接

如何安装swig.exe并配置环境变量_CDA答疑社区 https://www.cda.cn/discuss/post/details/6049742075777523b5dff658

配置好环境变量之后一定一定一定要重新启动cmd窗口，然后在执行安装库的命令！！！

否则还会提示error: command 'swig.exe' failed: No such file or directory
