嘿 stackoverflow 社区，我想在 google recolab 中使用 firefox geckodriver 为 python 运行 selenium。我最近发现了一篇关于这个主题的帖子，其中有一个答案@DebanjanB从前一段时间开始：https://stackoverflow.com/a/57553986/15163882。遗憾的是，提供的解决方案不再有效，我不知道如何修复它。
这是 stackoverflow 答案中的代码，应该下载并运行 geckodriver；
# install firefox, geckodriver, and selenium
!apt-get update
!pip install selenium
!apt install firefox-geckodriver
!cp /usr/lib/geckodriver /usr/bin
!cp /usr/lib/firefox /usr/bin
from selenium import webdriver
binary = '/usr/bin/firefox'
options = webdriver.FirefoxOptions()
options.binary = binary
options.add_argument('start-maximized')
options.add_argument('--headless')
browser = webdriver.Firefox(firefox_options=options, executable_path='/usr/bin/geckodriver')
browser.get('http://google.com/')
!cp /usr/lib/geckodriver /usr/bin结果出错，没有这样的文件，geckodriver 存储在/usr/bin/geckodriver. !cp /usr/lib/firefox /usr/bin也不起作用，/usr/lib/firefox是目录，不是文件。总的来说，代码失败了，但有以下例外：Process unexpectedly closed with status signal
这是完整的错误输出：
/usr/local/lib/python3.6/dist-packages/selenium/webdriver/firefox/webdriver.py in __init__(self, firefox_profile, firefox_binary, timeout, capabilities, proxy, executable_path, options, service_log_path, firefox_options, service_args, desired_capabilities, log_path, keep_alive)

更新#1
这是我最好的尝试，它将所有内容放在所需的所有路径中：
import sys,os
from os import system as o
!pip install selenium
def sudo_cmd(cmd):o('echo %s|sudo -S %s' % ('12345678', cmd))
sudo_cmd('apt-get update')
sudo_cmd('apt install firefox-geckodriver')
sudo_cmd('cp /usr/lib/geckodriver /usr/bin')
sys.path.insert(0,'/usr/lib/geckodriver')
from selenium import webdriver
options = webdriver.FirefoxOptions()
options.headless = True
options.add_argument('--no-sandbox')
driver = webdriver.Firefox(options=options, executable_path='geckodriver')
driver.get('https://www.google.com/')
但我仍然遇到同样的错误。
我还注意到 geckodriver.log 文件输出src/tcmalloc.cc:283] Attempt to free invalid pointer 0x7fa48e915160 Redirecting call to abort() to mozalloc_abort在设置代码出错之前。
远程服务器正在运行Linux-4.19.112+-x86_64-with-Ubuntu-18.04-bionic.
如果有人能帮助我，我会很高兴！
