python - SessionNotCreatedException : Message: Unable to create new service: ChromeDriverService with Selenium 3. 14.0 和 Python 3.7.3

Question

Python 3.7.3

Pycharm 2019.1.3

Selenium 独立3.14.0

Selenium 3.141.0

Java JDK 12.0.2

Windows 7

当我尝试使用远程网络驱动程序运行脚本时出现错误，我的java.version 不是我所期望的(预计版本至少为 12。):

我尝试重新安装 java JDK，但版本保持不变 - 1.8.0_221

我的Python代码:

driver = webdriver.Remote(
   command_executor='http://10.20.10.193:4444/wd/hub',
   desired_capabilities=DesiredCapabilities.CHROME)

driver.get('https://google.com')

设置 Selenium 服务器:

java -jar selenium-server-standalone-3.14.0.jar

我做错了什么？

Answer 1

此错误消息...

selenium.common.exceptions.SessionNotCreatedException: Message: Unable to create new service: ChromeDriverService
Build info: version: '3.14.0', revision: 'aacccce0', time: '2018-08-02T20:13:22.693Z'
System info: host: 'host_name', ip: 'localhost', os.name: 'Windows 7', os.arch: 'x86', os.version: '6.1', java.version: '1.8.0_221'
Driver info: driver.version: unknown

...暗示 ChromeDriver 未被识别。

您的主要问题是您使用的二进制文件版本之间不兼容，如下所示:

Selenium Client Driver页面提及:

• 支持的 Python 版本:

    Python 2.7, 3.4+
  

• 但是 selenium 3.141.0 上的列表页面仅包含:

• Python :: 2.7

• Python :: 3.4

• Python :: 3.5

• Python :: 3.6

因此可能仍然不支持 Python 3.7.3，您可能必须将 python 降级到相关版本。
