title: Your Ruby version is 2.1.0, but your Gemfile specified 2.0.0
body: <p>In my Gemfile I specified ruby version 2.0.0:</p>
  
  <pre><code>ruby '2.0.0'
  </code></pre>
  
  <p>But my console tells me I have 2.1.0dev:</p>
  
  <pre><code>$ ruby -v
  ruby 2.1.0dev (2013-09-16 trunk 42951) [x86_64-darwin12.4.0]
  </code></pre>
  
  <p>I am using rbenv and it tells my I don't have 2.1.0 installed, </p>
  
  <pre><code>$ rbenv versions
  system
  * 2.0.0-dev
  </code></pre>
  
  <p>Bundle update or bundle install says:</p>
  
  <pre><code>"Your Ruby version is 2.1.0, but your Gemfile specified 2.0.0"
  </code></pre>
  
  <p>but using 'rbenv local 2.0.0-dev' leaves me with ruby 2.1.0dev again. Furthermore:</p>
  
  <pre><code>$ rbenv global
  2.0.0-dev
  
  $ cat ~/.bash_profile:
  export PATH="$HOME/.rbenv/bin:$PATH"
  if which rbenv &gt; /dev/null; then eval "$(rbenv init -)"; fi
  </code></pre>
  
  <p>As far as I know, 2.1.0dev doesn't even exist yet. </p>
  
  <p>How can i get ruby 2.0.0 selected?</p>
