body: <p>I installed <code>ruby</code> with:</p>

  <p>I installed <code>cocoapod</code> with <code>$ sudo gem install cocoapods</code></p>

  <p>but I need <code>pod</code> Executable Path under <code>/usr/local/bin/</code> for Jenkins.</p>
  
  <p>Do I need to run additional install <code>cocoapod</code>  to <code>/usr/local/bin/</code>?</p>
  
  <p>And why from other examples I see pod installed under <code>/usr/local/bin/</code> and mine <code>/Users/snaggs/.rvm/rubies/ruby-2.3.3/bin/pod</code>?</p>
  
  <p>Thanks,</p>
