我正在尝试使用 Selenium 对网站进行一些自动化测试，但收到此异常：
Traceback (most recent call last):
File "guitester.py", line 22, in <module>
browser = webdriver.Firefox(executable_path=gecko_path, firefox_binary=binary)

selenium.common.exceptions.SessionNotCreatedException: Message: Unable to find a matching set of capabilities
我的 PATH 中有 geckodriver，并仔细检查了所有相关软件的版本。我的代码是基本的：
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
gecko_path = '/usr/local/bin/geckodriver'
binary = FirefoxBinary('/usr/bin/firefox')
browser = webdriver.Firefox(executable_path=gecko_path, firefox_binary=binary)
我已经尝试过使用和不使用 webdriver.Firefox() 包含的参数，并且无论哪种方式都得到相同的异常。其他帖子提到了不正确的版本，但我的研究表明我使用的所有东西都应该兼容。我正在使用python虚拟环境。
