Prepros failed to process Sass file version “GLIBC

Question

To learn and use Sass, I installed Prepros On Ubuntu 14.04 LTS. But every time i try to process an scss file (sass file) I get this error notification

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)

I checked using stings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX 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?

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

version "GLIBCXX_3.4.20" not found

The problem is that your libstdc++.so.6 is too old.

Versions of libstdc++ and their ABI's are documented here. GLIBCXX_3.4.19 corresponds to GCC-4.8.3, and GLIBCXX_3.4.20 to GCC-4.9.0.

To get a newer libstdc++.so.6, you need to upgrade your GCC. Here is how this could be done.
