в чем может быть проблема?

Шикарно! Спасибо. Надо еще сборку свг спрайта туда прикрутить

Всё по полочкам. Спасибо))

очень годная статья, спасибо огромное.

Спасибо за Ваши старания, статья и правда шикарная =))

У меня не обновляет автоматически когда я сохраняю HTML документ, в чем может быть бок? Подскажите плиз.

Предлагаю изменить путь для rimraf, чтобы он не затирал всю папку build и ускорить формирование проекта. Мы же хотим удалять только картинки, поэтому прописать clean: './build/img/.'

Спасибки, пригодилось

почему при написании gulp у меня выдает ошибку? Хотя все сделал по инструкции!

может кто ответить?

удали gulp 4.0.0

npm remove gulp

и установи 3.9.1

npm install gulp@3.9.1
