Please try to install the Ruby DevKit.

https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

[lit-uriy]

Ruby DevKit installed, and i run devkitvars.bat, to update PATH variable. I am instal mathematical gem manual, libxml-dev too. When I explicitly the manual installation of gems, no error occurs. There are a large number of gems that need to install, I can't do it all by hand.

@lit-uriy: check if you have installed: mingw-w64-x86_64-gcc via pacman -S mingw-w64-x86_64-gcc if your are using http://www.msys2.org/
