missing module 'del'

[finnigantime]

After calling npm install and trying to start the webserver, I get an error that module 'del' is missing. Installing it via npm install --save-dev del fixes it and allows the webserver to start successfully for me.

$ npm run serve

> react-three-renderer-example@1.0.0 serve /private/var/admin/Documents/GitHub/react-three-renderer-example
> gulp webpack-dev-server

Sorry I just came back to this bug and saw that the npm versions were mentioned in the logs.

I recommend trying with npm@3.5.2 and if it's still happening please reopen the issue.
