解决方法：

'sh' is not recognized as an internal or external command, operable program or batch file.

您需要将sh.exe添加到路径中。一些程序，如GitHub桌面（例如，C:\Users\bob\AppData\Local\GitHubDesktop\app-0.7.0\resources\app\git\usr\bin）或Cygwin都附带sh.exe。在

我推荐http://www.lfd.uci.edu/~gohlke/pythonlibs/#rpy2+例如pip install rpy2-2.8.6-cp36-cp36m-win_amd64.whl，正如康斯坦丁诺斯·伊万杰里迪斯所说，它使生活更容易。在
