Firefox會話未使用Selenium網格遠程驅動程序啟動-無法找到匹配的功能集

Question

java.version：“ 12.0.1”

硒服務器內部版本信息：版本：“ 3.141.59”

Firefox版本= 68

python版本= Python 3.7.2

我嘗試在硒網格上運行firefox並收到以下錯誤：selenium.common.exceptions.SessionNotCreatedException：消息：無法找到一組匹配的功能構建信息：版本：'3.141.59'，修訂版：'e82be7d358'，時間： '2018-11-14T08：25：53'系統信息：主機：'*****'，ip：'******'，操作系統名稱：'Windows 8.1'，os.arch：'amd64 '，os.version：'6.3'，java.version：'12 .0.1'驅動程序信息：driver.version：未知

這是我設置網格的方式：

java -jar selenium-server-standalone-3.141.59.jar -port 4444-角色集線器

在第二個cmd窗口上，我像這樣啟動firefox節點

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”

我嘗試了幾種功能選項的混合，包括使用json文件（功能列表）中的更詳細信息以及在我的python腳本中設置firefox節點，但我仍然遇到相同的錯誤。

這是我的python腳本代碼：

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()

在我的cmd窗口中，我還會收到這樣的遠程stacktrace錯誤：

這很長...如果需要，我可以將其余內容附加到問題上...

我建議降級到Java 8，並為您的節點使用config.json文件，如下所示：

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