  <p>another <a href="https://stackoverflow.com/questions/14970877/error-on-sudo-pod-install">post</a> suggested using the 'rm -rf ~/.cocoapods' command line
  but this caused my cocoapods to stop working all together for all project
  now which ever project I try to 'pod install' I get the 'Unable to find a specification for..' error</p>
  
  <blockquote>
    <p>[!] Unable to find a specification for <code>CorePlot (= 1.3)</code>.</p>
