Gulp 3.x is not compatible with Node.js 10, causing the issues documented in #28. Ultimately, the Gulp process should be upgraded to use version 4 of Gulp.

Some resources:

• npm install gulp@next talk from Gulp's primary maintainer
• Official Getting Started documentation
• Gulp 4 interview
• Slides and code from my DNN Summit presentation which compared 3.x to 4.x.
