installing ruby on mac

i'm having trouble following along and installing ruby on my mac.

I currently have ox x 10.9.2 on my computer.

Every time I try to go to github and download the osx-gcc installer, my computer keeps telling me that the file cannot be found or that I don't have access to the file i downloaded.

i went ahead and downloaded Xcode and also went to the developer site and downloaded command line osx for mountain lion.

is this essentially the same thing?

Thanks for the help!

Ruby should already be installed with OSX by default.

Enter terminal and type

$ruby -v

to find which version you have.

The default version is 1.9.3 or something close to that, which is outdated.

Update to the latest ruby, which should be 2.1.1 though rbenv. rbenv helps you manage the different versions of ruby you may have for different projects.

For example, you may need a certain set of gems or different version of ruby for your local/project enviornment, but you use a different set of tools for your global/default ruby/different project. https://github.com/sstephenson/rbenv

actually, i think it's on my comp now but i'm not sure how.

i type "ruby -v" into the terminal and then got this output:

$ ruby -v ruby 2.0.0p451 (2014-02-24 revision 45167) [universal.x86_64-darwin13] julians-MacBook-Pro:~ juliangallegos$

does this mean it's already installed?

Thanks!
