SCA fails running font-awesome task

I am attempting to run gulp (local, deploy or without a task) on unaltered versions of SCA 2+, in ubuntu 17.04 using nvm to change my node.js version. Elbrus with node v7.10.0 completes without issue. Anything older (Vinson with v4.8.3, Mont Blanc with v4.4.7 or Denali with v0.12.18) will build for a while then throw the following:

events.js:141
      throw er; // Unhandled 'error' event
      ^

SyntaxError: Invalid flags supplied to RegExp constructor 'u'

Global npm modules have been purged. Skipping font-awesome(line 38 in gulpfile.js) skips the error.

here is the solution faced same issue yesterday

1. You need to update the nodejs version to 'node-v6.10.3-linux-x64.tar.gz' if you are using 4.x.x or below (this works for me..) https://nodejs.org/dist/v6.10.3/
2. To Install nodejs got to

cd /usr/local tar --strip-components 1 -xzf /home/earth/node-v6.10.3-linux-x64.tar.gz

check the node version by node -v

4. Download Source code from file cabinet and extract it

   Web Site Hosting Files > Live Hosting Files > SSP Applications > NetSuite Inc. - SCA Elbrus> Development > _Sources-->SuiteCommerce Advanced Elbrus Release.zip

5. Go to Root directory and type 'npm install' command to install node dependencies

6. Type gulp in same directory. If it gives you error regarding sass then type below commands npm rebuild node-sass

Check you will get error in step 6, but npm rebuild node-sass will resolve that.
