Ruby + Rails + Debian

I tried a million different tutorials, and they all sucked, then my friend showed me the way.

1. comment or delete the lines currently in /etc/apt/sources.list
2. add the follow lines to /etc/apt/sources.list
   

   deb http://ftp.debian.org/debian/ etch main

   
   

   deb-src http://ftp.debian.org/debian/ etch main

   
   

   deb http://security.debian.org/ etch/updates main contrib

   
   

   deb-src http://security.debian.org/ etch/updates main contrib

   
   

   deb http://ftp.debian.org/debian/ testing main

   
   

   deb-src http://ftp.debian.org/debian/ testing main

   
   

   deb http://security.debian.org/ testing/updates main contrib

   
   

   deb-src http://security.debian.org/ testing/updates main contrib

   
   
3. Run the follow command:
   

   apt-get update

   
   
4. /etc/apt/apt.conf should contain:
   

   APT::Default-Release "stable";
   APT::Cache-Limit "16777216";
   

   
   
5. run:
   

   apt-get -t testing install ruby1.8
   apt-get -t testing install ruby1.8-dev
   apt-get -t testing install ri1.8
   apt-get -t testing install rubygems
   ln -s /usr/bin/ruby1.8 /usr/bin/ruby
   ln -s /usr/bin/ri1.8 /usr/bin/ri
   

   
   
6. install all the gems you want and use them!
   

All DONE!
