Install Rails 2 and Rails 3 with rvm on Debian 5 Lenny and above

First, we need to install some prerequisite stuff and we will provide do that
by executing this command on Terminal window:

$ sudo apt-get install subversion git-core autoconf bison sqlite3 zlib1g-dev libyaml-dev curl

Once this has been done we will provide to begin the installation of our ruby version manager
rvm pasting and executing the code below on a Terminal window:

$ bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )

After we should take a look to the post-installion tasks looking at the result of:

$ rvm notes

After rvm has been successfully installed we need to provide the amendment of our .bashrc. First, we need to look if there exist a line containing "return" and we need to substitute that one by:

if [[ -n "$PS1" ]] ; then

Next you scroll down until to the end of your .bashrc and you add this:

fi

Finally, you provide to give the path to rvm installation adding to the .bashrc:

[[ -s "/home/[YOURUSERNAME]/.rvm/scripts/rvm" ]] && source "/home/[YOURUSERNAME]/.rvm/scripts/rvm"

(Substitute your username instead of [YOURUSERNAME]) Now "rvm" should ready to work but we need before to open a new tab or close our Terminal window and open a new one. We check everything is fine giving this command:

rvm -v

This should show your rvm's version. After rvm's installation we can begin the installation of ours Rubies on Rails.

1. Installation of Rails2 This will begin by the installation of a supporting ruby version. So type now in terminal the following:

   $ rvm install 1.8.7

   After the task has been successfully done we select by rvm this ruby by:

   $ rvm use 1.8.7

   Now we can provide directly to Rail2's installation:

   $ rvm gem install -v=2.3.8 rails

   Check than your rails has been installed by:

   $ rails -v

   that should result in a href="rails 2.3.8" Is important now provide to reinstall the right rubygems version for our Rails2 by:

   $ wget http://rubyforge.org/frs/download.php/74140/rubygems-1.5.0.tgz

   $ tar zxvf rubygems-1.5.0.tgz

   $ cd rubygems-1.5.0

   $ ruby setup.rb

   Check the version of rubygems is correct:

   $ gem -v

   Finally, you should provide to check your Rails2's installation is working by:

   $ rails test

   that should result in producing the usual Rails2 application's scheme.

2. Installation of Rails3

   $ rvm install 1.9.2-head

   $ rvm use --default 1.9.2-head

   $ ruby -v

   $ rvm gem install --pre rails

   $ rails -v

   $ rails new ./testrails3

3. Do Not Forget to Take a Look..

   Feel Better on Debian Linux

Now Rails2 and Rails3 should both working together on your Debian :)
