title: Activesupport error while installing rails in jruby
body: <p>I installed jRuby using rvm. It's version is jruby-1.6.7.2 [ i386 ].
  Now I am trying to install rails on top of it.
  But I am getting following error</p>
  
  <blockquote>
    <p>ERROR:  Error installing rails:   activesupport requires Ruby version >= 1.9.3.</p>
  </blockquote>
  
  <p>I am using following command to install rails which I found in many answers on so itself.</p>
  
  <blockquote>
    <p>jruby -S gem install rails --pre --no-rdoc --no-ri</p>
  </blockquote>
  
  <p>I also tried passing --1.9 option to jruby so that it can use ruby 1.9 interpreter. But that also not working.</p>
  
  <blockquote>
    <p>jruby --1.9.3 -S gem install rails</p>
  </blockquote>
  
  <p>My RVM list is as follows : </p>
