How does gem setting work? How did gem get the installation files?

Question

when I wanted to install SASS , they told me to install ruby ​​on my car, fine.

then all i had to do was run the following code

gem install sass 

and now I'm done and I have SASS installed

my question at all.

How did the gem know what SASS was, and where did it get it from?

This is a cool thing, but I just want to know what happened backstage?

thanks

RubyGems is a package manager , like so many others. It depends on the central repository for hosting the installed packages. The command line tool extracts these packages from the central repository and installs them.
