Getting ` Error [ERR_REQUIRE_ESM]` while running `gulp` command

Question

I'm new to Gulp and trying to automate some tasks. Here's my environment setup: npm version: 8.1.0, node version 17.0.1, gulp CLI version 2.3.0 and gulp version 4.0.2

And here's my gulpfile.js:

// list of dependencies ( things require to run the below funcitions)
const { src, dest, watch, series } = require('gulp');
const sass = require('gulp-sass');
const prefix = require('gulp-autoprefixer');
const minify = require('gulp-clean-css');
const terser = require('gulp-terser');
const imagemin = require('gulp-imagemin');
const imagewebp = require('gulp-webp');



// create functions


// SCSS
function compilescss() {
    return src('src/scss/*.scss')
        .pipe(sass())
        .pipe(prefix('last 2 versions'))
        .pipe(minify())
        .pipe(dest('/dist/css'))
}


// JS
function jsmin(){
    return src('src/js/*.js')
        .pipe(terser())
        .pipe(dest('dist/js'))
}

// images
function optimizeimg() {
    return src('src/img/*.{jpg,png}')
        .pipe(imagemin([
            imagemin.mozjpeg({quality: 80, progressive: true}),
            imagemin.optipng({optiminzationLevel: 2})
        ]))
        .pipe(dest('dist/img'))
}


// webp images
function webpImage() {
    return src('dist/img/*.{jpg, png}')
        .pipe(imagewebp())
        .pipe('dist/img')
}


// create watchlist
function watchTask(){
    watch('src/scss/*.scss', compilescss);
    watch('src/js/*.js', jsmin);
    watch('src/img/*.{jpg,png}', optimizeimg);
    watch('dist/img/*.{jpg,png}', webpImage);
}



// default gulp
exports.default = series(
    compilescss,
    jsmin,
    optimizeimg,
    webpImage,
    watchTask
);

When I'm trying to run gulp command in the terminal. I'm getting errors like - Error [ERR_REQUIRE_ESM]: require() of ES Module E:\Projects\portfolio\node_modules\gulp-imagemin\index.js from E:\Projects\portfolio\gulpfile.js not supported.

I've tried solutions like - adding type:"module" in package.json and instead of require() used import but I couldn't make it work. So how can I fix this??? Thanks!

gulp-imagemin 8.0.0 and above are now ESM only. You can downgrade gulp-imagemin to 7.1.0 which is commonjs and it should work fine.

This package is now pure ESM. Please read this.
