title: ERROR: RVM Ruby not used, run `rvm use 1.9.1` first
body: <p>I am using Ubuntu 12.04 and installed ruby using rvm. I have recently upgraded ruby from 1.9.3 to 2.0.0. When I displays ruby version it shows 2.0.0.</p>
  
  <pre><code>$ ruby -v
  ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
  </code></pre>
  
  <p>When I try to start the solr server, it says a bundle is missing.</p>
  
  <pre><code>$ RAILS_ENV=development rake sunspot:solr:start
  Could not find unicode_utils-1.4.0 in any of the sources
  Run `bundle install` to install missing gems.
  </code></pre>
  
  <p>Then when I tried to <code>bundle install</code>, I am getting the following error.</p>
  
  <pre><code>$ bundle install
  ERROR: RVM Ruby not used, run `rvm use 1.9.1` first.
  </code></pre>
  
  <p>Listing the know rubies, I am getting the following MRI rubies.</p>
  
  <pre><code>$ rvm list known
  # MRI Rubies
  [ruby-]1.8.6[-p420]
  [ruby-]1.8.7[-p374]
  [ruby-]1.9.1[-p431]
  [ruby-]1.9.2[-p320]
  [ruby-]1.9.3[-p448]
  [ruby-]2.0.0-p195
  [ruby-]2.0.0[-p247]
  [ruby-]2.0.0-head
  ruby-head
  </code></pre>
  
  <p>As I said before, I recently updated ruby to 2.0.0 and removed all other ones. After that everytime I restart the computer, I need to do <code>bundle install</code> or do other pre requisites to start the server. I am sure the bundles are installed, but some rvm ruby version is the reason. Any help would be appreciated.</p>
  
  <p>Edit 1 : I tried <code>rvm use 2.0.0-p247</code>, following is the output which I got.</p>
  
  <pre><code>$ rvm use 2.0.0-p247
  
  RVM is not a function, selecting rubies with 'rvm use ...' will not work.
  
  You need to change your terminal emulator preferences to allow login shell.
  Sometimes it is required to use `/bin/bash --login` as the command.
  Please visit https://rvm.io/integration/gnome-terminal/ for a example.

  <p>and still I am getting the same error, when <code>bundle install</code></p>
