1. Try running this simple Nightmare scripts  , it returns nothing:

  1 Nightmare = require ('nightmare');
  2 var show = process.argv.length>2 && process.argv[2]=='true'
  3 console.log('show = '+show)
  4 
  5 const nightmare = Nightmare({ show: show });
  6 
  7 nightmare
  8   .goto('http://google.com')
  9   .cookies.get({
 10     path: '/query',
 11     secure: true
 12   })
 13   .then((cookies) => {
 14     // do something with the cookies
 15     console.log('done')
 16     process.exit()
 17   })
 18 
 
 2. Turns out Nightmare uses Electron which requires X-window installed

  3. we fix it by using xvfb 
  
      3.1  installl xvfb :
      sudo apt-get install -y xvfb x11-xkb-utils xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic x11-apps clang libdbus-1-dev libgtk2.0-dev libnotify-dev libgnome-keyring-dev libgconf2-dev libasound2-dev libcap-dev libcups2-dev libxtst-dev libxss1 libnss3-dev gcc-multilib g++-multilib

      3.2  run it (instead of just node example.js)
       xvfb-run node example.js
       
 4. it works!!!
