Set-up doesn't work (Windows)

[lcundiff]

Steps:
Bundle Install (ran without error)
npm install (ran without error)
ran "gulp" :
"ReferenceError: primordials is not defined in node" error came up.
I fixed it by upgrading to gulp 4.0
ran "gulp" again:
"libsass bindings not found when using node-sass in nodejs" error appeared.
I fixed it by running: "npm uninstall --save-dev gulp-sass" and then: "npm install gulp-sass --save-dev"

I then ran "gulp" again:
assert.js:385
throw err;
^

This error appeared which seems to be an issue with the code? Couldn't debug further.
