Question

我真的不确定我的节目有什么问题。它上周正在运行，我甚至没有更改任何代码，但现在当我运行我的刮刀，在firefox打开后，没有任何事情发生很长一段时间，然后我得到以下错误

Traceback (most recent call last):
File "C:/Users/usernameredracted/PycharmProjects/scraper - Copy/demospider.py", line 179, in <module>

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: connection refused

我尝试了（selenium.common.exceptions.WebDriverException: Message: connection refused）中列出的解决方案，但这给我带来了不同的错误

OSError=[WinError 2] The system cannot find the file specified
Program install error!

有关如何做的任何建议？

试试这个。

首先更新selenium：pip install -U selenium然后更新您的geckodriver

https://github.com/mozilla/geckodriver/releases

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = False
driver = webdriver.Firefox(capabilities=firefox_capabilities)

https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver

使用Selenium 3.0及更高版本，您不需要做任何事情就可以使用木偶，因为它默认启用。

这可能是牵线木偶中的一些未知错误，尝试使用上面的代码禁用它以使用好的旧geckodriver，如果失败也向我们显示提示。

Selenium实际上并没有控制Firefox
