问题描述
我正在尝试使用python和硒在Firefox的无头模式下自动执行某些情况.我想，我做了我需要的所有设置，但仍未初始化webdrvier.
I am tryin to use python an selenium to automate some cases on firefox headless mode. I think, I did every settings that I need but still webdrvier is not initialized.
我的问题是在执行我的代码后大约30-60秒获得了异常，并且异常消息并不清晰，实际上消息部分为空.如您所见，在无头模式下运行的geckodriver.log firefox.
My problem is getting the exception approximately 30-60 sec after executing my code and exception message is not clear actually message section is empty. As you can see on the geckodriver.log firefox running in headless mode.
我使用Firefox 56.0.1，python 3.6，硒3.141.0.这是我的代码和日志；

推荐答案
此错误消息...
selenium.common.exceptions.InvalidSessionIdException: Message:
...表示 GeckoDriver 无法启动/产生新的 WebBrowsing会话，即 Firefox浏览器会话.
...implies that the GeckoDriver was unable to initiate/spawn a new WebBrowsing Session i.e. Firefox Browser session.
根据日志消息 geckodriver版本号不再反映在启动时，因此您必须使用:
As per the log messages geckodriver version number is no longer reflected on startup, so you must be using:
GeckoDriver 版本=> 0.22.0(2018-09-15)
但是您正在使用:
- 硒3.141.0
- Firefox 56.0.1
- Selenium 3.141.0
- Firefox 56.0.1
因此，您的主要问题是 GeckoDriver ， Selenium 和 Firefox 二进制文件之间的不兼容性您正在使用.
So, your main issue is the incompatibility between the version of the GeckoDriver, Selenium and Firefox binaries you are using.
如果您使用的是 GeckoDriver -硒- Firefox 组合，则需要针对
If you are using GeckoDriver-Selenium-Firefox combo, you need to follow the following compatibility chart for the Supported platforms:
