when I wanted to install SASS, I have been told to install ruby on my machine, ok fine.
then all I had to do is to run the following code
gem install sass
and now I am done, and I have SASS installed
my question is in general..
How did gem knows what SASS is, and from where did it get it ?
It is a cool thing but I just want to know what happened behind the scenes ?
Thanks
RubyGems is a package manager like many others. It depends on a central repository to host installable packages. The command line tool fetches these packages from the central repository and installs them.
See RubyGems FAQ and Introduction.
