How to upgrade Angular CLI to the latest version : <p>Using <code>ng --version</code> I got:</p>

<blockquote>
  <p>@angular/cli: 1.0.0</p>
</blockquote>

<p>which is not the latest release available.</p>

<p>Since I have Angular CLI globally installed on my system, in order to upgrade it I tried:</p>

<p><code>npm update angular-cli -g</code></p>

<p>But it does not work, because it stays to 1.0.0 version.</p>
