Errors Installing KeystoneJS on OSX
<p>I ran npm install -g generator-keystone from the root directory in OSX but got the following errors:</p>

<pre><code>npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated CSSselect@0.4.1: the module is now available as 'css-select'
npm WARN deprecated minimatch@0.3.0: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated CSSwhat@0.4.7: the module is now available as 'css-what'
</code></pre>

<p>When I try and use yo keystone I then get:</p>

<pre><code>-bash: yo: command not found
</code></pre>

<p>I did try and update these packages using:</p>

<pre><code>npm update -g minimatch
npm update -g CSSselect
npm update -g CSSwhat
</code></pre>

<p>Any advice would be greatly appreciated.</p>

<p>(PS I have Node 4.4.3 and Mongo Shell 3.2.7 installed)</p>
