WebDriverException:消息:进程意外关闭,状态信号 |如何在 Google Colaboratory 中 运行 Selenium Firefox Geckodriver?

WebDriverException: Message: Process unexpectedly closed with status signal | How to run Selenium Firefox Geckodriver in Google Colaboratory?

嘿 Whosebug 社区,我想 运行 selenium for python,在 google recolab 中使用 firefox geckodriver。我最近发现了一个关于这个主题的 post ,其中有 @DebanjanB from a while ago: 的回答。遗憾的是,提供的解决方案不再有效,我不知道如何修复它。

这是来自 Whosebug 答案的代码,应该下载 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,没有这个文件,geckodriver存放在/usr/bin/geckodriver!cp /usr/lib/firefox /usr/bin 也不行,/usr/lib/firefox 是目录,不是文件。总的来说,代码失败,异常:Process unexpectedly closed with status signal

这是完整的错误输出:

更新#1

这是我最好的尝试,它把所有东西都放在了所有需要的路径中:

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 文件在设置代码出错之前输出 src/tcmalloc.cc:283] Attempt to free invalid pointer 0x7fa48e915160 Redirecting call to abort() to mozalloc_abort

远程服务器 运行正在 Linux-4.19.112+-x86_64-with-Ubuntu-18.04-bionic

如果有人能帮助我,我会很高兴!

遇到同样的错误。经过一些实验找到了这个解决方案:

!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
