我试图在我的虚拟ubuntu shell上安装和使用 selenium chromedriver,我按照一步一步的各种教程,但似乎仍然有一些错误...经过许多研究的问题,我找不到任何答案。
下面是我尝试运行的小代码:
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')
我添加了chrome_options,这要感谢我在各种主题上找到的建议。但是我真的不明白为什么它是必要的?
不幸的是,我的程序发送给我以下错误,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.)
有人已经有这个问题或有任何建议吗?

A common cause for Chrome to crash during startup is running Chrome as **
root** user (**
administrator**) on Linux. While it is possible to work around this issue by passing
--no-sandboxflag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.
第一条错误消息...
...表示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客户端的Release Notesv3.8.0,
chrome_options
已弃用:options
、firefox_options
、chrome_options
和ie_options
现已弃用。*溶液
在初始化ChromeDriver/Chrome会话时,您需要使用**
options
**而不是chrome_options
。因此,您的代码块实际上将是:disho6za2#
您可以使用以下代码片段在服务器上运行seleniumcrawler(ubuntu中没有GUI,没有X窗口):

我在谷歌上搜索Ruby错误,但发现了这个。对一些人来说可能会有帮助。
我错误地设置了水豚会话(它本身依赖于 selenium )
