loadstarterkit fails with TypeError [ERR_INVALID_ARG_TYPE] when using Node 9

[ThePeach]

I am using Pattern Lab Node- Gulp Edition v1.4.0 on Linux.

Expected Behavior

When loading a starterkit I should have no problems and this should be the output:

$ npm run gulp -- patternlab:loadstarterkit --kit=starterkit-mustache-demo

> edition-node-gulp@1.4.0 gulp /home/peach/public_html/edition-node-gulp
> gulp "patternlab:loadstarterkit" "--kit=starterkit-mustache-demo"

Loading engines from the core...


Loading engines from the edition or test directory...

  mustache: good to go

Done loading engines.

Actual Behavior

When using Node 9 I get the following:

+1 exactly the same issue unfortunately. Obviously you are able to manually install these but it would be much better if it worked as per documentation.. I'm using patternlab-node edition gulp from here https://github.com/pattern-lab/edition-node-gulp/releases/tag/v1.3.4 as per download page.
