Cannot uninstall angular-cli : <p>I've tried several times to uninstall my angular-cli in order to update it but even if I follow the instructions provided on github:</p>

<ul>
<li>npm uninstall -g @angular/cli</li>
<li>npm cache clean</li>
<li>npm install -g @angular/cli@latest</li>
</ul>

<p>When I check using the command ng --version I still get the old version :</p>

<pre><code> angular-cli: 1.0.0-beta.26

 node: 7.7.1
 os: darwin x64
</code></pre>

<p>How can i fix this issue? Thanks</p>
