  </code></pre>
  
  <p>I tried to do <code>npm i -g npm</code> but it couldn't update itself, it just kept throwing the same error above.</p>
  
  <p>When I run <code>npm -v</code> it says <code>5.5.1</code> it seems the latest version is currently <code>5.8.0</code>.</p>
  
  <p>I tried deleting the folder and running the repair function on the node.js installer, but it didn't replace the module.</p>
