title: After node reinstalled: "Cannot find module 'internal/util/types' "
body: <p>So I had removed node from my computer (mostly, I thought) a couple months ago, and today I reinstalled it. Node's working okay, but when I try to test npm I get this message:</p>
  
  <pre><code>$ npm
  module.js:549
      throw err;
      ^
  
  Error: Cannot find module 'internal/util/types'

  <p>I tried using "npm rebuild" as I've seen suggested, but that has no impact on anything. I'm using Node v8.11.2 on Windows (hell if I know what version of NPM). Any clues?</p>
