“无法使用匹配的功能集”在Windows 10上使用Firefox的selenium / geckodriver

Question

版本：

• geckodriver 0.26.0（在PATH环境变量中）

• 硒3.141.0

• Firefox 75.0

• python 3.8.2

• Windows 10

当我尝试：

from selenium import webdriver

driver = webdriver.Firefox()
driver.get('https://seleniumhq.org/')

我明白了：

    raise exception_class(message, screen, stacktrace)

当我尝试：

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

cap = DesiredCapabilities().FIREFOX
cap["marionette"] = False
driver = webdriver.Firefox(capabilities = cap)
driver.get('https://seleniumhq.org/')

IEDriver对于IE可以正常工作

我安装了Windows Visual Studio，并以https://github.com/mozilla/geckodriver/releases表示应该。

我该怎么做才能使这项工作？
