问题描述
我正在尝试在 Windows 中安装 cplex API。我对这个程序不是很熟悉，所以我一直在使用 R 博主的这个链接
https://www.r-bloggers.com/2017/01/using-cplex-in-r-installing-cplexapi-in-windows-10/
使用 windows 命令提示符后，我得到以下响应：
R CMD build --no-build-vignettes --no-manual --md5 C:\Users\Rharris\Desktop\cplexAPI
* checking for file 'C:\Users\RHARRIS\Desktop\cplexAPI/DESCRIPTION' ... OK

Warning in system("sh ./configure.win") : 'sh' not found
ERROR: configuration Failed for package 'cplexAPI'

configure.win 文件中似乎有错误，但下载后我根本没有对其进行编辑。当我打开它是一个空白文件时，我不确定这是否是我应该做的。
如果有人在这里提供任何见解，我们将不胜感激。
解决方法
看着这个错误消息“'sh' not found”，我怀疑你应该安装 cygwin 以便安装可以使用 BourneShell。 如果失败，我想你可以联系包https://www.th-koeln.de/personen/gabriel.gelius-dietrich/的作者。 干杯，
