Windows 10: Compilation issue

[ClaireGuerin]

Hello,

I tried to install rPython following the instructions given in the README file of this GitHub repository. I am using Windows 10, R.3.3.0, Python 2.7 (stored in "C:/Python27").
When running install("C:/Program files (x86)/rPython"), I get the following error:

Installing rPython
"C:/PROGRA~1/R/R-33~1.0/bin/x64/R" --no-site-file --no-environ --no-save  \
  --no-restore --quiet CMD INSTALL "C:/Program files (x86)/rPython"  \
  --library="C:/Users/Claire/Documents/R/win-library/3.3" --install-tests

Any idea on what might be causing this, and how to fix it? I am not even sure whether the problem comes from Rtools or rPython...

I experienced something like this too. I performed a completed reinstall of rPython and that worked for me.
