Nightwatch chromedriver
<p>I can't run nightwatch to run tests on chrome.  </p>

<p>Here is my modified nightwatch.json that I downloaded from the nightwatch example:</p>

<pre><code>{
  "src_folders" : ["./examples/tests"],
  "output_folder" : "./examples/reports",
  "custom_commands_path" : "./examples/custom-commands",
  "custom_assertions_path" : "",
  "globals_path" : "./examples/globals.json",
  "live_output" : false,

  "selenium" : {
    "start_process" : false,
    "server_path" : "/lib/sel-serv.jar",
    "log_path" : "",
    "host" : "127.0.0.1",
    "port" : 4444,
    "cli_args" : {
      "webdriver.chrome.driver" : "/lib/chromedriver/chromedriver.exe",
      "webdriver.ie.driver" : "",
      "webdriver.firefox.profile" : ""
    }
  },

  "test_settings" : {
    "default" : {
      "launch_url" : "http://localhost",
      "selenium_host" : "127.0.0.1",
      "selenium_port" : 4444,
      "silent" : true,
      "disable_colors": false,
      "screenshots" : {
        "enabled" : false,
        "path" : ""
      },
      "chrome":{
      "desiredCapabilities" : {
        "browserName" : "chrome",
        "javascriptEnabled" : true,
        "acceptSslCerts" : true
      }
      }
    },


      "desiredCapabilities": {
        "name" : "test-example",
        "browserName": "chrome"
      },
      "globals" : {
        "myGlobal" : "some_sauce_global"
      },
      "selenium" : {
        "start_process" : false
      }
  }
}
</code></pre>

<p>And I get this error message:</p>

<pre><code>ERROR There was an error while starting the test runner:

<p>I also found a older post that says you have to create new file in root directory so give it a try and nothing happened</p>
