I'm newest in Selenium tests. I have some question. I installed Nightwatcher, and this is my config file:

 "src_folders": ["/home/project"],
 "output_folder": "./reports",
 "custom_commands_path": "",
 "custom_assertions_path": "",
 "page_objects_path": "",
 "globals_path": "/home/project/globals.js",

 "selenium" : 
 "start_process" : true,
 "server_path" : "/opt/selenium/selenium-server-standalone.jar",
 "log_path" : "",
 "port" : 4444,
 "cli_args" : 
 "webdriver.chrome.driver" : "./bin/chromedriver"
 
 ,

 "test_settings" : 
 "default" : 
 "selenium_port" : 9515,
 "selenium_host" : "localhost",
 "default_path_prefix" : "",
 "screenshots" : 
 "enabled" : true,
 "path" : "./screen"
 ,

 "desiredCapabilities": 
 "browserName": "chrome",
 "javascriptEnabled": true,
 "chromeOptions" : 
 "args" : ["--no-sandbox", "--headless", "--disable-gpu", "--disable-extensions"]
 ,
 "acceptSslCerts": true
 
 
 

And this is my global.js file:

const chromedriver = require('chromedriver');
 module.exports = 
 before: function(done) 
 chromedriver.start();
 done();
 ,
 after: function(done) 
 chromedriver.stop();
 done();
 

Chromedriver was downloaded from off site http://chromedriver.chromium.org/downloads and unzip in home_project/bin. But when i try to start test i have err like this:

# nightwatch --test ya.js
There was an error while starting the test runner:

Error reading external global file failed: using /home/project/globals.js:
Error: Cannot find module 'chromedriver'

Any ideas?
