Windows: Compiler issue while installing in R ; Errors in 'ymake_conf.py' about catboost HOT 8 CLOSED

You also need Visual C++ 2015 Build Tools. Our integration with R on Windows is kinda fragile, but it works. We are investigating alternatives to improve this. For now, R binding installation is much more stable on Darwin and Linux.

@ferrr Thanks a lot..Its working now.
Got something in between..you might want to take a look at it.

I installed both 2015 and 2017 (for Windows 10).
2015 components: Desktop development with C++, Visual Studio extension development.
2017 components: Windows 10 SDK as a part of Visual C++ build tools.
I'm sure some components are redundant but it has worked

Visual C++ 2017 Build Tools only worked for me, not 2015

Please tell me which component should be installed from Visual C++ 2017 Build Tools ? I have VS 2017 Community Edition with installed VC 2017 tools for build classic C++ applications - but problem still there.
