[ALUG] Installing Ruby & Rails

[zachariahn]

Hi Guys,
As preparation for the upcoming presentation, I think it'd be nice if we 
all have ruby installed and working on our machines. I will post links to 
where Ruby + Rails can be downloaded and installed for different machines. 

For Windows & Mac just go to the following link and download the Rails 
Installer and pick the one that has ruby 1.9.3 and just install
http://railsinstaller.org/en

Please note that, for those using MacOS, Macs come with ruby installed but 
sometimes the version installed is not the one that we need so just check 
by going into the terminal and type the command ruby -v, if you have 1.9.3 
then check the rails version you have as well type rails -v, otherwise just 
download the installed from the site and install.

Once installation is finished, you can see if it was successfull by running 
the same commands ruby -v & rails -v. For those on Linux, just run the 
command 

sudo apt-get install ruby1.9.1-full

then when installation is complete, to install rails just run the following 
command 

gem install rails --version 3.2 

For those that used the installer downloaded from the above link, you will 
see that it also installed other things like git, sqlite, rvm(for mac), 
etc. If you are on Linux you might wanna install git manually if you don't 
have it already

Thats it, if you are having and problem just ask
