title: Rvm: Cannot uninstall bundler 1.1.0
body: <p>I have a rails 3.0.2 project I'd like to install, despite the fact that most of my new projects are 3.2+</p>
  
  <p>I went to run bundle install and got the following message:</p>
  
  <pre><code>Bundler could not find compatible versions for gem "bundler":   In Gemfile:
      rails (= 3.0.2) ruby depends on
        bundler (~&gt; 1.0.0) ruby
  
    Current Bundler version:
      bundler (1.1.0)
  
  This Gemfile requires a different version of Bundler.
  Perhaps you need to update Bundler by running `gem install bundler`?
  </code></pre>
  
  <p>"Not a problem" I think to myself. "New gem set, uninstall bundler 1.1.0, install 1.0.0 and we're away".</p>
  
  <p>But no.</p>
  
  <p>RVM will not let me uninstall 1.1.0. I can install other versions, I can uninstall other versions, but I can't uninstall 1.1.0. If I type gem list bundler, it shows 1.1.0, but if I type gem uninstall bundler (with or without version tag) it says 'gem not installed'.</p>
  
  <p>Any time I create a new gemset it's installed by default…and I can't uninstall.
  Any idea what's going on here? RVM version 1.9.2, if it makes a difference</p>
