Error install rpy2: 'sh' is not recognized as an internal or external command, operable program or batch file


I try install rpy2 but I have this error below.

I read in the web that the problem it's the Environment Variables but I have C:\Rtools\bin and C:\Program Files\R\R-3.2.2\bin in System Variable Path.

what am I doing wrong?

Error:

C:\Users\rmalveslocal>pip install rpy2
