Функция Gulp Watch не отображает онлайн изменения в браузере.

Question

Вот мой gulpfile. js код.

"use strict";

var gulp = require("gulp"),
    autoprefixer = require("gulp-autoprefixer"),
    cssbeautify = require("gulp-cssbeautify"),
    removeComments = require('gulp-strip-css-comments'),
    rename = require("gulp-rename"),
    sass = require("gulp-sass"),
    cssnano = require("gulp-cssnano"),
    rigger = require("gulp-rigger"),
    uglify = require("gulp-uglify"),
    watch = require("gulp-watch"),
    plumber = require("gulp-plumber"),
    imagemin = require("gulp-imagemin"),
    run = require("gulp4-run-sequence"),
    rimraf = require("rimraf"),
    webserver = require("browser-sync");



/* Paths to source/build/watch files

Работает хорошо, за исключением одной вещи. Там нет онлайн отслеживания изменений (глоток часы). Проект редактируется в папке «src /», но файлы сохраняются в другой папке «dist /». Может быть, это проблема?
