var scanner = require('i18next-scanner');

gulp.task('i18next', function() {
    return gulp.src(['pages/**/*.{js,html}'])
        .pipe(scanner({
            lngs: ['en', 'id', 'zh_TW', 'zh_CN', 'th', 'ms', 'my'], // supported languages
            resource: {
                // the source path is relative to current working directory
                loadPath: 'static/locales/{{lng}}/{{ns}}.json',

                // the destination path is relative to your `gulp.dest()` path
                savePath: 'locales/{{lng}}/{{ns}}.json'
            }
        }))

Had similar issues yesterday. Deleted my 'lock' file and node_modules directory, did a fresh install, with the latest version of acorn as a new dependency. Still didn't work. Finally got around it by adding a "resolutions" entry in my package.json, pointing to the scanner's internal version.

"resolutions": {
    "i18next-scanner/**/acorn": "6.1.1"
  }

It is open source, therefore you are the team.

It stated that you might have two acorn copies in your project. https://github.com/acornjs/acorn-private-class-elements/blob/master/index.js#L22-L24

  if (cur !== acorn.Parser) {
    throw new Error("acorn-private-class-elements does not support mixing different acorn copies")
  }

Try npm ls to see all the occurrences in the dependency tree.

Remove both node_modules and package-lock.json and do a fresh install should work.
