sass (Syntactically Awesome Style Sheet) is an extension to CSS that makes it easy to write and maintain CSS, but is not supported by browsers.

A "PhantomJS sass build" refers to the process of compilation of SASS (which is nice to write) into CSS (which browsers understand), done in the 3rd party product PhantomJS (which is a "headless browser", a browser without GUI).

Inside PhantomJS, which doesn't understand SCSS either, runs a javascript code called "Sencha Fashion", a so-called "transpiler" that converts SASS to CSS.

Now, your version of PhantomJS throws error 137, which is a pain to find out without a concise error message. You can check whether you have enough free system memory and which version of PhantomJS is installed and possibly revert to an older version , to name a few possibilities a short google search has brought up .
