title: Angular 4, angularfire2, Metadata version mismatch
body: <p>I've got the following error</p>
  
  <blockquote>
    <p>Metadata version mismatch for module c:/..../node_modules/angularfire2/index.d.ts, found version4, expected 3.</p>
  </blockquote>
  
  <p>And if I go and check in my <strong>package.json</strong>, I have angularfire2 on version 5.0.0-rc.4, and firebase on 4.6.2.
  <a href="https://i.stack.imgur.com/CdFoS.png" rel="noreferrer">see screenshot for details</a></p>
  
  <p>I tried changing the version of angularfire2 and firebase to previous versions but nothing worked.</p>
  
  <p>Any suggestions ?
  Thank you.</p>
