在Eclipse中使用Selenium Firefox时遇TypeError：executable_path参数无效

问题原因 #

Selenium 4.x版本起，webdriver.Firefox()不再支持executable_path参数，该参数已被移除，驱动路径需要通过Service类来指定管理。

解决步骤 #

1. 你已经导入了Service类，直接用它封装GeckoDriver路径
2. 创建Service实例并传入驱动路径，再将service参数传递给webdriver.Firefox()
3. 移除无意义的driver = webdriver.Firefox()空初始化代码

修改后的核心代码片段 #

# 浏览器配置
options = Options()
options.add_argument('--start-maximized')
options.add_argument('--disable-extensions')

driver_path = r'C:\\x\\x\\x\\x\\geckodriver-v0.33.0-win32\\geckodriver.exe'

# 初始化Service实例
service = Service(executable_path=driver_path)
# 通过service参数启动Firefox Driver
driver = webdriver.Firefox(service=service, options=options)

额外优化提示 #

代码中使用的driver.find_element_by_xpath()属于Selenium旧版API，已被弃用，建议替换为新版写法：

# 旧写法（已弃用）
texto_columnas = driver.find_element_by_xpath('/html/body/div[7]/main/div[4]/div/section[4]/section/div[1]/ul')

# 新写法
texto_columnas = driver.find_element(By.XPATH, '/html/body/div[7]/main/div[4]/div/section[4]/section/div[1]/ul')
