Here is the error message after I try to run my app

[15:32:01] Starting 'default'...

[15:32:01] Plumber found unhandled error:

GulpUglifyError: unable to minify JavaScript

Caused by: SyntaxError: Unexpected token keyword «function», expected
punc «,»

File: /home/*******/myfile.js Line: 81

my gulp file:

const gulp = require('gulp')

const uglify = require('gulp-uglify')

const babel = require('gulp-babel')

const plumber = require('gulp-plumber')

const del = require('del')



gulp.task('default', ['conf'], () => gulp.src('src/app/**/*.js')

  .pipe(plumber())

  .pipe(babel())

  .pipe(uglify())

  .pipe(gulp.dest('dist')))



gulp.task('conf', ['package'], () => gulp.src('./src/conf/*').pipe(gulp.dest('dist/conf')))



gulp.task('package', ['clean'], () => gulp.src(['./package.json']).pipe(gulp.dest('dist/')))



gulp.task('clean', () => del(['dist/**/*']))

If I correctly understand the problem, my code has to be transpiled to es5 by babel, so here is the .babelrc

{

  "plugins": [

    "transform-class-properties", 

    "babel-plugin-transform-runtime",

    "transform-es2015-shorthand-properties",

    ["babel-plugin-root-import", {

      "rootPathSuffix": "src/app"

    }]

  ],

  "presets": ["es2015"]

}

Here is the code from line 81 (where the comments begin) from myfile.js.

export default class Scraper {

  // ...

  /**

   * Converts a html string to a cheerio object

   * @param {String} html The html string

   * @return {Object} The cheerio object

   */

  htmlToDom(html) {

    // https://bugs.chromium.org/p/v8/issues/detail?id=2869

    // https://github.com/cheeriojs/cheerio/issues/263

    if(typeof global.gc === 'function') {

      global.gc()

      html = (' ' + html).substr(1)

    }

    return cheerio.load(html)

  }



  static absolute(location, relative) {

  //...

}

First I thought maybe the shorthanded version causing the problem, but I have transform-es2015-shorthand-properties installed, and in an older project I use the very same skeleton, without this plugin.
