/node_modules/jpegtran-bin/vendor/jpegtran: Syntax error: "(" unexpected in file

Hi,

I have commented out one section that references a giant image library and attached a small images directory images.tar.gz

My grunt file is running successfully locally on my MacBook pro but not on my Ubuntu Plesk server, not sure what is wrong I get the following error message:

Running "imagemin:dynamic" (imagemin) task
Warning: Error: Error: write EPIPE/var/www/vhosts/staging.specialistreferrals.co.nz/httpdocs/node_modules/jpegtran-bin/vendor/jpegtran: 1: /var/www/vhosts/staging.specialistreferrals.co.nz/httpdocs/node_modules/jpegtran-bin/vendor/jpegtran: Syntax error: "(" unexpected
 in file images/CM_logo.jpg Use --force to continue.

Have also tried getting the latest version of grunt-contrib-imagemin.

For that I did

npm uninstall --save-dev grunt-contrib-imagemin

and then

npm install --save-dev grunt-contrib-imagemin

Grunt file code:

module.exports = function(grunt) {

  // Project configuration.
  grunt.initConfig({
