Browserify + Gulp + Babelify ~ import' and 'export' may appear only with 'sourceType: module

Question

I'm working on a project and want to use gulp to automate some tasks, to compile js and other code. I'm using Browserify and Babelify in combination with the babel-eslint to set my sourcetype to module however i still get this ParseError when I'm trying to import node_modules in my main.js file

ParseError: 'import' and 'export' may appear only with 'sourceType: module'

Is there a way to fix this?

My gulp file

const gulp = require('gulp');
const sass = require('gulp-sass');
const minify = require('gulp-minify');
const rename = require('gulp-rename');
const browserify = require('browserify');
const babelify = require('babelify');
const tap = require('gulp-tap');
const flatmap = require('gulp-flatmap');
const logger = require('gulplog');
const source = require('vinyl-source-stream');
const sourcemaps = require('gulp-sourcemaps');
const buffer = require('vinyl-buffer');
const babel = require('gulp-babel');
const plumber = require('gulp-plumber');

gulp.task('default', function () {
  let b = browserify({
    entries: './resources/js/main.js',
    debug: true,
    cache: {},
    packageCache: {},
    fullPaths: true,
    transform: [babelify.configure({
      presets: ['@babel/preset-env']
    })]
  })

  return b.bundle()
    .pipe(source('main.js'))
    .pipe(buffer())
    .pipe(sourcemaps.init({loadMaps: true}))
    // Add other gulp transformations (eg. uglify) to the pipeline here.
    .on('error', (error) => {
      logger.error(error);
    })
    .pipe(sourcemaps.write('./'))
    .pipe(gulp.dest('./public/js/'));
});
