title: Installing Ruby 'rbenv: shell integration not enabled...' - have homebrew installed on macOS Mojave 10.14.6
body: <p>I'm no developer or even remotely close, sorry please excuse my ignorance. I'm just trying to do a few things to improve my knowledge and communication with the Dev team.  I'm trying to install Ruby for use with our system.  I installed the most recent version of Homebrew and installed Ruby 2.5.1 (I think).</p>
  
  <p>In the terminal I see:</p>
  
  <pre><code>rbenv shell 2.5.1
  rbenv: shell integration not enabled. Run `rbenv init' for instructions.
  rbenv init
  # Load rbenv automatically by appending
  # the following to ~/.bash_profile:
  eval "$(rbenv init -)"
  </code></pre>
  
  <p>I have tried several things mentioned on various web boards, no luck.</p>
  
  <p>I open the <code>.bash_profile</code> and <code>eval "$(rbenv init -)"</code> is the 1st entry.</p>
  
  <p>Is this a problem? If yes, can I proceed?</p>
