gulp -v CLI version: 2.2.0 Local version: 4.0.2

node -v v12.6.0

Facing the same issue - gulp 3.x did not work with the latest node, gulp 4.0 gets the error as reported here.

Perhaps https://www.sitepoint.com/how-to-migrate-to-gulp-4/ is relevant.

Ralph does not support gulp4 - you'll have to force installation of gulp3.
