title: Prepros failed to process Sass file version "GLIBCXX_3.4.20" not found on Ubuntu 14.04
body: <p>To learn and use Sass, I installed <strong>Prepros</strong> On <strong>Ubuntu 14.04</strong> LTS. But every time i try to process an scss file (sass file) I get this error notification </p>
  
  <pre><code>Failed to Process File sass/style.scss
  /usr/lib/x86_64-linux-gnu/libstdc++.so.6:
  version "GLIBCXX_3.4.20" not found
  (required by /usr/lib/prepros/resources/extensions/node-sass.asar.unpacked/node-modules/node-sass/build/Release/binding.node)
  </code></pre>
  
  <p>I checked using <code>stings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX</code> and confirmed that indeed it seems GLIBCXX versions are only available up to 3.4.19. Is there a way to install version 3.4.20 (and higher) on Ubuntu 14.04 LTS? or a workaround for either that or using Prepros? or using SASS in general? </p>
  
  <p>Please keep in mind I've installed a lot of very version specific software and I'm very reluctant about upgrading. Any help would be really highly appreciated</p>
