How to make bin script available for npm package installed locally
<p>I read on the npm documentation that you can't use bin scripts of locally installed packages.</p>

<p>So, how <code>gulp</code> can be launched as bin command when installed locally?
What's making it available when locally installed, I reviewed the <code>gulp</code> <code>package.json</code> and the bin scripts, I don't found any answer.</p>
