Why is Gulp not finding connected modules?

Question

gulp.js

There is a gulpfile:

const gulp = require('gulp');
const lesstocss = require('./gulp/tasks/style');
const includetohtml = require('./gulp/tasks/include');
const svgsprite = require('./gulp/tasks/sprite');
const minifyImg = require('./gulp/tasks/imagemin');
const fonts = require('./gulp/tasks/fonts');
const del = require('./gulp/tasks/clean');
const serve = require('./gulp/tasks/serve');

const dev = gulp.parallel(lesstocss, fonts, minifyImg, svgsprite, includetohtml);
const build = gulp.series(del, dev);
module.exports.start = gulp.series(build, serve);
module.exports.build = build;

Each task is separated into a separate file. For example, the imagemin.js task file:

const gulp = require('gulp');
const img = require('gulp-imagemin');

module.exports = function image() {
  return gulp.src('src/img/**')
    .pipe(img([
      img.mozjpeg({quality: 75, progressive: true}),
      img.svgo()
  ]))
      .pipe(gulp.dest('build/img'));
}

Error while running commands.

Error: Cannot find module './gulp/tasks/imagemin'
Explain why it can't find my module files? What am I doing wrong?
Individually, each task starts and runs successfully.

Answer 1

Issue resolved. Unfortunately, my carelessness.
Paths are correct in gulpfile. The path was entered incorrectly in one of the tasks.
Question removed.
