title: Npm updates sucessfully, but still shows old version
body: <p>When I do a <code>npm -v</code> I see that I am still on 5.6.0. And keep getting prompts to do a <code>npm i npm</code>.</p>
  
  <p>But I've done a <code>sudo npm install npm@latest -g</code> and double checked with a <code>npm outdated -g --depth=0</code> to see that my global npm is at the latest already (6.0.0).</p>
  
  <p>How do I resolve this conflict? Is the npm I'm using the latest or is it still the old one? Is it because my global is linked incorrectly or something?</p>
