我正在Ubuntu服务器上运行Jupyter Notebook。我尝试使用ChromeDriver运行以下Selenium代码。但是,我遇到了下面的错误。如果我在Ubuntu终端中运行下面的代码行,它会返回下面的输出。有人知道问题可能是什么吗?我对Ubuntu还不太熟悉。
Ubuntu代码:
which google-chrome
输出:
/usr/bin/google-chrome
Jupyter Notebook 代码:
driver = webdriver.Chrome(executable_path=os.path.abspath("/home/username/chromedriver"), chrome_options=chrome_options)
错误:

更新:
chrome_options.add_argument("no-sandbox")
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument("--headless")
由于某种原因,在我的代码中添加了以上这些行后,问题得以解决。我在下面的文章中找到了这段代码。
在ubuntu上执行Selenium UI测试用例时出现“未知错误:DevToolsActivePort文件不存在”的错误
addArguments("--no-sandbox"); // Bypass OS security model
和addArguments("--disable-extensions"); // disabling extensions
的形式。如果您需要进一步的帮助,请告诉我。 - undetected Selenium
