Answer 1

From the description you are using Windows?
Downloading Ruby I'm using Ruby 1.9.3-p545 for version 2 there are still many gems not ported, and immediately download the DEVELOPMENT KIT for the selected version of Ruby, required for some gems.
Install Ruby and see that the "Path" checkbox is checked during the installation process, if you forgot, then right-click on "Computer" - "Properties" - "Advanced system settings" - on the additional tab, click "Environment Variables" - select the line Path and click edit, add a semicolon to the path to ruby, I have: C:\Ruby193\bin;
After that, ruby ​​will be available from the command line.
Next, unpack the dev kit, I made a Devkit folder in the Ruby folder and shoved it there, in ruby ​​cmd or let's say I use the shell that comes with git (mingw32), go to the devkit folder and write ruby ​​dk.rb init, it will be created config.yml file, then write ruby ​​dk.rb install and that's it, the dev kit will be installed.
Then everything is simple: gem install sass compass
