[英]WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally with ChromeDriver Chrome and Selenium through Python on VPS
[英]WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally error using ChromeDriver Chrome and Selenium Python
我正在尝试在我的虚拟 ubuntu shell 上安装和使用 Selenium chromedriver,我一步一步地按照各种教程进行操作,但似乎仍有问题......经过对该问题的多次研究后,我找不到任何答案。
这是我试图运行的小代码:
from selenium import webdriver
from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-extensions')
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get('https://google.com')
由于我在各种主题上找到的建议,我添加了 chrome_options。 但是我真的不明白为什么有必要?
不幸的是,我的程序向我发送了以下错误,我在这里卡住了,我不知道该怎么办:

(The process started from chrome location /usr/bin/chromium-browser is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
有人已经遇到过这个问题或对此有任何建议吗?
第一条错误信息...

...暗示ChromeDriver无法启动/生成新的浏览上下文,即Chrome 浏览器会话。
根据Selenium的python客户端v3.8.0 chrome_options
的发行说明已弃用:
浏览器选项参数现在作为
options
跨驱动程序标准化。firefox_options
、chrome_options
和ie_options
现已弃用。
在初始化 ChromeDriver/Chrome 会话时,您需要使用options
而不是chrome_options
。 所以有效地你的代码块将是:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-extensions')
driver = webdriver.Chrome(executable_path='/path/to/chromedriver', options=chrome_options)
driver.get('https://google.com')
您可以使用以下代码片段在服务器(没有 GUI 的ubuntu,框中没有可用的X 窗口)上运行selenium爬虫:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
driver = webdriver.Chrome(executable_path='/usr/lib/chromium-browser/chromedriver', options=chrome_options)
driver.get('https://google.com')
我在谷歌上搜索 ruby 错误,但发现了这个。 对于某些人来说,它可能会有所帮助。
我错误地设置了水豚会话(它本身依赖于硒)
# WRONG
session = Capybara::Session.new(:selenium_chrome)
# CORRECT, see headless added
session = Capybara::Session.new(:selenium_chrome_headless)
