title: RVM Not Changing Ruby Version on Mac
body: <p>I'm trying to change my ruby versions on Mac and even though it says its on the right ruby version (2.3.4), it still doesn't work.</p>
  
  <p>Example output:</p>
  
  <pre><code>:~ my_username$ cd my_project_name
  :my_project_name my_username$ which ruby
  /Users/my_username/.rvm/rubies/ruby-2.3.4/bin/ruby
  :my_project_name my_username$ ruby -v
  ruby 2.3.4p301 (2017-03-30 revision 58214) [x86_64-darwin16]
  :my_project_name my_username$ bundle install
  Ignoring executable-hooks-1.3.2 because its extensions are not built. Try: gem pristine executable-hooks --version 1.3.2
  Ignoring gem-wrappers-1.3.2 because its extensions are not built. Try: gem pristine gem-wrappers --version 1.3.2
  Your Ruby version is 2.5.0, but your Gemfile specified 2.3.4
  :my_project_name my_username$
  </code></pre>
  
  <p>And RVM list, and then attempting to bundle install for my project:</p>
  
  <pre><code>:my_project_name my_username$ rvm list
  
  rvm rubies
  
  =* ruby-2.3.4 [ x86_64 ]
     ruby-2.4.0 [ x86_64 ]
     ruby-2.4.1 [ x86_64 ]
     ruby-2.4.2 [ x86_64 ]
  
  # =&gt; - current
  # =* - current &amp;&amp; default
  #  * - default
  
  :my_project_name my_username$ bundle install
  Ignoring executable-hooks-1.3.2 because its extensions are not built. Try: gem pristine executable-hooks --version 1.3.2
  Ignoring gem-wrappers-1.3.2 because its extensions are not built. Try: gem pristine gem-wrappers --version 1.3.2
  Your Ruby version is 2.5.0, but your Gemfile specified 2.3.4
  :my_project_name my_username$
  </code></pre>
  
  <p>As you can see, I have both 2.3.4 installed and set to the current ruby version but it doesn't detect it in my directory. I've closed and retried several times in a new terminal window.</p>
