我试图让seleniumbase geckodriver（firefox）工作，它似乎告诉我，我的驱动程序文件是一个目录

E   NotADirectoryError: [Errno 20] Not a directory: '/usr/local/lib/python3.8/dist-packages/seleniumbase/drivers/geckodriver'
====================================================== short test summary info =======================================================

我试着只给它目录，它告诉我它需要这个文件。
我怎样才能让壁虎司机在 selenium 基地工作？
代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox('/usr/local/lib/python3.8/dist-packages/seleniumbase/drivers/geckodriver')
#driver = webdriver.Firefox('/usr/bin/geckodriver')
driver.get("https://www.python.org")
print(driver.title)
search_bar = driver.find_element_by_name("q")
search_bar.clear()
search_bar.send_keys("getting started with python")
search_bar.send_keys(Keys.RETURN)
print(driver.current_url)
driver.close()

安装方法：

seleniumbase install geckodriver

以及

apt install firefox-geckodriver

相同的错误，两个驱动程序文件。
更新：
我的两个司机位置
