Selenium webdriver 在Selenium网格上运行chrome浏览器面临的问题

我可以在Selenium网格上的firefox浏览器上运行测试用例，但在Chrome浏览器上运行测试时遇到了问题，这似乎是一种配置问题

运行测试时出现以下错误：-

org.openqa.selenium.WebDriverException: unknown error: cannot find Chrome binary
(Driver info: chromedriver=2.20.353124  (035346203162d32c80f1dce587c8154a1efa0c3b),platform=Linux 3.13.0-63-generic x86_64) (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 504 milliseconds
Build info: version: '2.48.2', revision: '41bccdd', time: '2015-10-09 19:59:12'

我正在使用以下命令运行节点：-

export PATH=$PATH:/root/ChromeDriver
java -jar selenium-server-standalone-2.48.2.jar -port $1 -role node -hub http://localhost:4444/grid/register -timeout 1800000 -nodeConfig nodeconfig.json -Dwebdriver.chrome.driver="/root/ChromeDriver/chromedriver"

-Dwebdriver.chrome.driver="/root/ChromeDriver/chromedriver"

下面是我的nodeconfig.json

{
  "capabilities":
  [
    {
      "browserName": "firefox",
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver"
    },
    {
      "browserName": "chrome",
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver"
    }
  ],
  "configuration":
     {
       "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
       "maxSession": 5,
       "register": true,
       "registerCycle": 5000,
       "hubPort": 4444,
      "hubHost": 127.0.0.1
    }
}

我还使用以下命令添加了二进制路径：-

export PATH=$PATH:/root/ChromeDriver
java -jar selenium-server-standalone-2.48.2.jar -port $1 -role node -hub http://localhost:4444/grid/register -timeout 1800000 -nodeConfig nodeconfig.json -Dwebdriver.chrome.driver="/root/ChromeDriver/chromedriver"

-Dwebdriver.chrome.driver="/root/ChromeDriver/chromedriver"

有人能指出我做错了什么吗？

错误并不是说它找不到chromedriver二进制文件

错误告诉您Selenium找不到Chrome浏览器本身的安装位置。请检查chrome浏览器的路径
