I am following the course CS50's Web Programming with Python and JavaScript and we have to use SASS among other tools. I installed cygwin in my windows and has been working fine for almost everything (git, atom, etc.) but now I am trying to install SASS with no success. I follow this instructions: https://gist.github.com/Geraint/1600659 and they seem to work fine. The only problem is that the link to the RubyGems instructions seems to be broken. Still, it seems to me that I do have ruby and gem.
When I try the command:
$ gem install sass
I get:
ERROR: Could not find a valid gem 'Autorizado/bin' (>= 0) in any repository
ERROR: Possible alternatives: authorizable, authorization, authorization-san, auto_admin, auto_ria_api
WARNING: You don't have /home/Usuario in your PATH,
gem executables will not run.
Building native extensions. This could take a while...
ERROR: Error installing sass:

You might have to install separate package for the ruby development
environment, ruby-dev or ruby-devel for example.
extconf failed, exit code 1
Gem files will remain installed in /home/Usuario Autorizado/.gem/ruby/2.6.0/gems/ffi-1.12.2 for inspection.

Here is also a screen shot, I think it has something to do with my PATH but I have not been able to find a solution. My current folder has two - words (Usuario Autorizado) I do not know it this is also a problem and how to solve it.

I already tried this:
gem sources --add https://rubygems.org/
Explained here: "Could not find a valid gem in any repository" (rubygame and others) but it did not work.
I would really appreciate any help...
