title: Ruby get reset to the previously installed version
body: <p>I have ruby 2.3.0 and 2.3.1 installed via chruby and:</p>
  
  <pre><code>$ cat ~/.ruby-version
  ruby-2.3.1
  </code></pre>
  
  <p>But each time I open a new terminal window, it gets reset <code>2.3.0</code>. </p>
  
  <pre><code>$ cd my_rails_app
  $ rails s
  Your Ruby version is 2.3.0, but your Gemfile specified 2.3.1
  </code></pre>
  
  <p>but </p>
  
  <pre><code>$ cat Gemfile
  source 'https://rubygems.org'
  
  ruby '2.3.1'
  </code></pre>
  
  <p>and for some reason:</p>
  
  <pre><code>$ chruby
   * ruby-2.3.0
     ruby-2.3.1
  </code></pre>
  
  <p>Therefore I alwasys have to do:</p>
  
  <pre><code>$ chruby    ruby-2.3.1
  </code></pre>
