title: Can't uninstall global npm packages after installing nvm
body: <p>I've found several threads related to this issue but none seem to deal with my case specifically and I've been unable to solve using the suggestions I've found. </p>
  
  <p>When I run <code>npm uninstall -g "some package"</code> </p>
  
  <p>it just returns: <code>up to date in .043s</code> <em>- And the global package remains.</em></p>
  
  <p>For example I'm trying to <code>uninstall babel-cli</code> and after <code>running npm uninstall -g babel-cli</code> I'm still able to use the <code>cli</code>. </p>
  
  <p>This started after I uninstalled <code>node</code> and <code>npm</code> and reinstalled using <code>nvm</code>. I'm wondering if I missed something while uninstalling <code>node</code> and it's causing the issue. I checked my dot files and noticed I still have a <code>.npm</code> outside of <code>.nvm</code>. Is that normal? Thanks in advance for any suggestions.</p>
