title: Rails: Error installing rmagick - ERROR: Failed to build gem native extension
body: <p>I am trying to run one project on my local machine. I installed Ruby and Rails on my Mac OS system. It is working properly. I can create a new project and can run it properly without any error, but when I try to run the existing project it says that we have to <code>bundle install</code>. When I run that command I get the following error:</p>
  
  <pre><code>"An error occurred while installing rmagick (2.13.2), and Bundler cannot continue.
  Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling."
  </code></pre>
  
  <p>When I run <code>gem install rmagick -v '2.13.2'</code> it gives me the following error:</p>
  
  <pre><code>ERROR:  Error installing rmagick:
  ERROR: Failed to build gem native extension.
