嗨,任何人都知道发生了什么,或者我如何调试错误,如下所示。我所做的步骤是使用 setup hub 命令并将节点注册到集线器。在命令寄存器节点之后。我可以看到日志为

The node is registered to the hub and ready to use 

但是,当我运行测试脚本时,错误打印为:

selenium.common.exceptions.SessionNotCreatedException: Message: Unable to create new service: ChromeDriverService

二进制版本:

  • selenium 独立版本:3.14.0
  • selenium远程驱动版本:selenium==3.14.1
  • python版本:3.6.4

脚本:

import os
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

driver = webdriver.Remote(command_executor='http://localhost:4444/wd/hub',
desired_capabilities=DesiredCapabilities.CHROME)

设置中心:

#java -jar /Users/admin/selenium-server-standalone-3.14.0.jar -host localhost -role hub

注册节点:

#java -jar /Users/admin/selenium-server-standalone-3.14.0.jar -role node

错误:

../lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py:242: SessionNotCreatedException

最佳答案

这个错误信息...

selenium.common.exceptions.SessionNotCreatedException: Message: Unable to create new service: ChromeDriverService

...暗示 ChromeDriver 无法启动/生成新的 ChromeDriverService

命令 和您使用的二进制文件版本之间的不兼容性 存在一些问题,如下所示:

  • 您的JDK 版本1.8.0_91,它非常古老
  • JDK 升级到最新级别 JDK 8u181 .
  • 要注册一个 Selenium Grid Hub,您需要使用以下命令:

    >java -jar /Users/admin/selenium-server-standalone-3.14.0.jar -role hub
  • 要为 ChromeDriverChrome 注册一个 Selenium Grid Node,您需要传递 ChromeDriver 的绝对路径 以及Registration URIKeyValue,如下所示:

    >java -Dwebdriver.chrome.driver=/path/to/chromedriver.exe -jar /Users/admin/selenium-server-standalone-3.14.0.jar -role node -hub http://<IP_GRID_HUB>:4444/grid/register
  • 我觉得你的代码块不错。
