title: nodemon not working: -bash: nodemon: command not found
body: <p>I'm on a Mac running El Capitan. I have node v5.6.0 and npm v3.6.0. 
  When I try to run nodemon, I get: </p>
  
  <pre><code>-bash: nodemon: command not found
  </code></pre>
  
  <p>I thought this may mean that I didn't have nodemon installed, so when I tried to install it using...</p>
  
  <pre><code>sudo npm install -g nodemon
  </code></pre>
  
  <p>...I get this:</p>
  
  <pre><code>npm ERR! Darwin 15.2.0

  <p>If it makes a difference, I'm trying to run nodemon on a project that uses Express v4.13.1</p>
  
  <p>Thanks for any help you can offer!</p>
