WebDriverException：Message：进程意外关闭，状态信号|如何在Google Colboratory中运行Selenium Firefox Geckodriver？ [英] WebDriverException: Message: Process unexpectedly closed with status signal | How to run Selenium Firefox Geckodriver in Google Colaboratory?

问题描述

嘿Stackoverflow社区，我想用Google recolab中的Firefox geckodriver为python运行Selenium。我最近找到了一个关于这个话题的帖子，里面有一个来自前段时间@DebanjanB的回答：https://stackoverflow.com/a/57553986/15163882。遗憾的是，提供的解决方案不再起作用，我想不出如何修复它。

这是堆栈溢出答案中的代码，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导致错误，没有这样的文件，geckodriver存储在/usr/bin/geckodriver中。!cp /usr/lib/firefox /usr/bin也不起作用，/usr/lib/firefox是目录，不是文件。总体而言，代码失败并出现异常：Process unexpectedly closed with status signal

以下是完整的错误输出：

WebDriverException: Message: Process unexpectedly closed with status signal

更新#1

这是我最大的努力，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/')

但我仍然收到相同的错误。

我还注意到geckodriver.log文件在安装代码错误之前输出src/tcmalloc.cc:283] Attempt to free invalid pointer 0x7fa48e915160 Redirecting call to abort() to mozalloc_abort。

远程服务器正在Linux-4.19.112+-x86_64-with-Ubuntu-18.04-bionic上运行。

如果有人能帮我，我会很高兴的！👍

推荐答案

出现相同错误。经过一些实验，找到了这样的解决方案：

!apt-get update
!pip install selenium
!apt install firefox-geckodriver
!cp /usr/lib/geckodriver /usr/bin
!cp /usr/lib/firefox /usr/bin

t = '''
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(options=options, executable_path='/usr/bin/geckodriver')
browser.get('http://google.com/')
print(browser.page_source)

'''
with open("main.py", 'w') as file:
  file.write(t)

!sudo python3 main.py
