Error after uninstalling npm packages
<p>I have uninstalled the npm packages 'grunt-cli' and 'tsd' using the command:</p>

<pre><code>sudo npm uninstall -g grunt-cli 
sudo npm uninstall -g tsd
</code></pre>

<p>But now, when I list all npm packages:</p>

<pre><code>npm -g ls --depth=0
</code></pre>

<p>I get this error. There is no such file or directory. This is correct since I just uninstalled them...</p>

<pre><code>/usr/local/lib
├── bower@1.7.1
├── browserify@12.0.1
├── express-generator@4.13.1
├──  error: ENOENT: no such file or directory, open '/usr/local/lib/node_modules/grunt-cli/package.json
├── npm@3.5.3
├──  error: ENOENT: no such file or directory, open '/usr/local/lib/node_modules/tsd/package.json
└── typescript@1.8.9
</code></pre>

<p>Why do I get this error? How to completely remove grunt-cli and tsd? What does ENOENT mean? (tried googling it...)</p>
