title: Ruby on Rails Mac OSX Mavericks issues after RVM install
body: <p>I have been learning Ruby on Rails for a couple of months, and everything was working.</p>
  
  <p>Then, for the needs of a tutorial, I tried to install RVM, in order to downgrade my setup to older versions of Ruby and Rails.</p>
  
  <p>And since then, I kept running into troubles.</p>
  
  <p>For instance, anytime I launch a new Terminal session, here is what I get:</p>
  
  <pre><code>You are using '.rvmrc', it requires trusting, it is slower and it is not compatible with other ruby managers,
  you can switch to '.ruby-version' using 'rvm rvmrc to [.]ruby-version'
  or ignore this warning with 'rvm rvmrc warning ignore /Users/Thibaud/work/.rvmrc',
  '.rvmrc' will continue to be the default project file in RVM 1 and RVM 2,
  to ignore the warning for all files run 'rvm rvmrc warning ignore all.rvmrcs'.

  <p>Two questions:</p>
  
  <ol>
  <li><p>How can I resolve the errors appearing in my Terminal? (see above)</p></li>
  <li><p>Since I do not know what got broken in my install, I am wondering whether I should unsintall the whole Ruby on Rails environment and set it up again to get a clean install: Is this a good idea? If so, how can it be achieved?</p></li>
  </ol>
