Что от меня хочет Node.js?

Question

[hellcaster]

Когда я запускаю gulpfile (а именно gulp html), по Node.js говорит, что я не выполнил какие-то обещания
[20:12:49] Starting 'html'...
(node:4548) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): [object Object]
(node:4548) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

(мне кажется, что это что-то с include)

package.json

"scripts": {
    "test": "gulp style",
    "build": "gulp build",
    "start": "npm run build && gulp serve"
  },

Answer 1

[hellcaster]

Проблема была не в gulp или node.js, а в путях при include (нужно указывать от файла gulpfile.js, а не от текущего файла)

Answer 2

[ixon]

Это всего лишь предупреждение.

Отказ. Предупреждение. Отклонения от необработанных обещаний устарели. В будущем обещание отклонения, которое не обрабатывается, приведет к завершению процесса Node.js с ненулевым кодом выхода.

Но оно у меня не работает далее. У меня 1 файл на половину сделался, а второй и третий не обновляются (не добавляются include, srcset и не переносятся в другую папку)
