title: NVM install node won't change NPM global modules root folder
body: <p>Hi I've just upgrade Node to v9.3.0 and copied my NPM global modules from the last installed version:</p>
  
  <pre><code>nvm install 9.3.0 --reinstall-packages-from=9.2.0
  </code></pre>
  
  <p>But when I do </p>
  
  <pre><code>npm root -g
  </code></pre>
  
  <p>It still says </p>
  
  <pre><code>/Users/user/.nvm/versions/node/v9.2.0/lib/node_modules
  </code></pre>
  
  <p>How do I upgrade Node with NVM and automatically change NPM global modules root folder to the latest version as well?</p>
