java.version: '12.0.1'

硒服务器构建信息：版本：'3.141.59'

火狐版本 = 68

python 版本 = Python 3.7.2

我尝试在 selenium 网格上运行 firefox 并收到以下错误：selenium.common.exceptions.SessionNotCreatedException：消息：无法找到一组匹配的功能构建信息：版本：'3.141.59'，修订：'e82be7d358'，时间： '2018-11-14T08:25:53' 系统信息：主机：'*****'，ip：'******'，os.name：'Windows 8.1'，os.arch：'amd64 '，os.version：'6.3'，java.version：'12.0.1' 驱动程序信息：driver.version：未知

这就是我设置网格的方式：

java -jar selenium-server-standalone-3.141.59.jar -port 4444 -role hub

在第二个 cmd 窗口上，我像这样启动 firefox 节点

java -Dwebdriver.gecko.driver=C:\Selenium\geckodriver.exe -jar selenium-server-standalone-3.141.59.jar -port 5557 -role node -browser "browserName=firefox,platform=WINDOWS,maxInstances=1"

我尝试了几种功能选项的组合，包括使用 json 文件（功能列表）和我的 python 脚本中更详细的功能选项来设置 firefox 节点，但我仍然遇到相同的错误。

这是我的python脚本代码：

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

cap = DesiredCapabilities.FIREFOX.copy()

cap['browserName'] = 'firefox'
cap['platform'] = "WINDOWS"

driver = webdriver.Remote(command_executor='http://localhost:4444/wd/hub',
                          desired_capabilities=cap)
driver.get("https://www.google.co.in/")
print(driver.title)
driver.quit()

我在我的 cmd 窗口上也收到这样的远程堆栈跟踪错误：

这很长...如果需要，我可以将其余部分附加到问题中...

我建议降级到 Java 8 并为您的节点使用 config.json 文件，如下所示：

 {
   "capabilities": [
      {
       "browserName": "firefox",
       "platform": "WIN7",
       "maxInstances": 5
      }
   ],
   "hub": "http://<hub ip>:<hub port>"
  }
