Need help with gulpfile.js. What's wrong?

Question

gulp.js

I am a box and this is my first attempt. Made almost by analogy with the given habrahabr.ru/post/208890
my tree:

|--/stylus
|--/jade
|--/js
|--/build // Каталог релиза
|--/public // Каталог разработки
|--package.json
|--gulpfile.js

I have no one to ask in real time what is wrong with it and what should be done / written differently. I would be very grateful)
the problems started with lr = require('tiny-lr')
here is my attempt https://www.dropbox.com/s/c4fhb1sit9luj1d/gulpfile...

Answer 1

What exactly is that problem?
Install all these dependencies in the gulpfile folder described in var using the command:

npm install gulp tiny-lr и так далее через пробел их все --save-dev
