SessionNotCreatedException：消息：无法创建新服务：使用 Selenium 3.14.0 和 Python 3.7.3 的 ChromeDriverService

Question

Python 3.7.3

Pycharm 2019.1.3

selenium 独立版 3.14.0

硒 3.141.0

Java JDK 12.0.2

Windows 7

当我尝试使用远程 webdriver 编写运行脚本时出现错误，我的 java.version 不是我预期的（预期版本至少为 12。）：

我已经尝试重新安装 java JDK 但版本保持不变 - 1.8。0_221

我在 python 中的代码：

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

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

设置硒服务器：

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

我做错了什么？

Answer 1

这个错误信息...

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

...表示 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页面上的列表只包括：
Python :: 2.7
Python :: 3.4
Python :: 3.5
Python :: 3.6

所以可能 Python 3.7.3 仍然不受支持，您可能需要将 python 降级到相关版本。
