大家好，stackexchange 社区，我想在 google recolab 中运行 selenium for python，使用 firefox geckodriver。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不久前：https://stackoverflow.com/a/57553986/15163882。遗憾的是，提供的解决方案不再有效，而且我不知道如何修复它。
这是来自 stackoverflow 答案的代码，用于下载并运行 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导致错误，没有这样的文件，geckodriver 存储在 中/usr/bin/geckodriver。!cp /usr/lib/firefox /usr/bin也不起作用，/usr/lib/firefox是一个目录，而不是文件。 总的来说，代码失败，但出现以下异常：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，它将所有内容放在需要的所有路径中：
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/')
但我仍然收到同样的错误。
我还注意到，geckodriver.log 文件src/tcmalloc.cc:283] Attempt to free invalid pointer 0x7fa48e915160 Redirecting call to abort() to mozalloc_abort在安装代码出现错误之前输出。
