title: Homebrew: "curl: (60) SSL certificate: unable to get local issuer certificate"
body: <p>I was trying to install Homebrew and then Tensorflow on my Mac. After typing the following command</p>
  <pre><code>/usr/bin/ruby -e &quot;$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)&quot;
  </code></pre>
  <p>(from <a href="http://brew.sh/" rel="nofollow noreferrer">Homebrew</a>) to the terminal, I got the following error message:</p>
  <blockquote>
  <p>curl: (60) SSL certificate problem: unable to get local issuer certificate</p>

  <p><strong>Update:</strong> The Mac version is OS X El Capitan 10.11.5</p>

  <p>ps. I would really appreciate if you could provide me a solution with some explanation. This is the first time I use a Mac OS.</p>
