Problems Occurred when windows Installed ruby

  question, ruby

Originally, I wanted to install SASS, saying that ruby should be installed first. I downloaded ruby. There was a problem preparing for installation.
The questions are as follows:

I tried the online method, but it couldn’t be solved, and then I downloaded this rubygems.rb file.
But where should I put it?
Also, if I want to use sass, is there anything else available besides ruby?
Please give your advice
