Error when run "npm run dev"

[elfman]

I just clone this repository and didn't modify any thing, when I run "npm run dev" in terminal, it shows errors. Here is the log.

@elfman I'll look into this later. For now try a different commit. Most probably I've introduced a small bug in the latest one.

@birdofpreyru I removed the folder 'node_modules/' and run npm install to install again, it could work now, I don't know why. Sorry for wasting your time.
