如果我从外部启动webdriver并将量角器指向URL，我的量角器测试运行得很好。
如果我设置量角器以启动我的webdriver服务器：
seleniumServerJar: '/usr/local/lib/node_modules/protractor/selenium/selenium-server-standalone-2.42.2.jar',
chromeDriver: '/usr/local/lib/node_modules/protractor/selenium/chromedriver',
然后测试失败
Starting selenium standalone server...
Selenium standalone server started at http://X.X.X.X:37711/wd/hub
/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver/promise.js:1539
var result = fn();

任何可能导致此问题的想法？
