title: unable to remove node-modules/
body: <p>I don't understand why this time I can't remove my folder node_modules/ from a node project that I want to delete...</p>
  
  <p>usually <code>npm uninstall</code> do a great job, <code>npm rm</code> should also work, <code>npm prune</code> even for precise packages, but here I can delete nothing ?</p>
  
  <p>for exemple when I run <code>sudo npm uninstall node_modules/</code> I get :</p>
  
  <pre><code>npm WARN server@1.0.0 No description
  npm WARN server@1.0.0 No repository field.
