Don't want to compress gulp imagemin files?

Question

gulp.js

Hello everyone, I ran into such a problem that galp does not want to compress pictures, namely, it writes Here is the section where the code for compression is registered, help, I can’t find anything about this for half an hour.
[23:34:14] gulp-imagemin: Minified 0 images

gulp.task('image-compress', function() {
  return gulp.src('./assets/app/img/**/*.*')
  .pipe(plumber())
  .pipe(imagemin({ 
    progressive: true,
    optimizationLevel:3,
    svgoPlugins: [{removeViewBox: false}],
    use: [pngquant()],
    interlaced: true
  }))
  .pipe(gulp.dest('assets/build/img'));
});

PS pictures throws, but does not compress.

Answer 1

Why is imagemin-pngquant not giving a result?
