NPM not working (Cannot find module 'internal/fs' - nodejs)
<p>NPM error on update. I recently update to Node version 7.x. Now npm is not working. <br/></p>

<p>I am unable to locate the error, it may be due to - <br/>
<code>npm ERR! Cannot find module 'internal/fs'</code>. <br/> <br/>
 I get the following when I run <code>sudo npm update -g</code> -</p>

<pre><code>npm ERR! Linux 3.13.0-101-generic
