title: Cannot uninstall angular-cli
body: <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>
