问题描述

我在 ubuntu 服务器上运行一个 jupyter notebook.我正在尝试使用 chromedriver 运行下面的 selenium 代码.我收到下面的错误，但如果我在 Ubuntu 终端中运行下面的代码行，它会返回下面的输出.有谁知道问题可能是什么?我对 ubuntu 还是很陌生.

I’m running a jupyter notebook on ubuntu server. I’m trying run the selenium code below using chromedriver. I’m getting the error below but if I run the line of code below in Ubuntu terminal it returns the output below. Does anyone know what the issue might be? I’m still pretty new to ubuntu.

Ubuntu 代码:

which google-chrome

输出:

/usr/bin/google-chrome

jupyter 笔记本代码:

jupyter notebook code:

driver = webdriver.Chrome(executable_path=os.path.abspath("/home/username/chromedriver"), chrome_options=chrome_options)

更新:

chrome_options.add_argument("no-sandbox")
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument("--headless")

出于某种原因，将上面的行添加到我的代码中解决了这个问题.我在下面的帖子中找到了代码.

For some reason adding the lines above to my code solved the issue. I found the code in the post below.

未知错误:DevToolsActivePort 文件不存在在 ubuntu 上执行 Selenium UI 测试用例时出错

推荐答案

这个错误信息...

WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
  (Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Linux 4.15.0-46-generic x86_64)

...暗示 ChromeDriver 无法启动/生成新的 WebBrowser 即 Chrome 浏览器 会话.

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

您的主要问题是您使用的二进制文件版本之间的不兼容性，如下所示:

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• 您正在使用 chromedriver=74.0.3729.6
• chromedriver=74.0.3729.6 的发行说明 明确提及以下内容:

支持 Chrome v74

• 也许您使用的是最新的 GAed 版本的 Chrome 浏览器，即 chrome=73.x

所以 ChromeDriver v74.0.3729.6 和 Chrome 浏览器 v73.x

• 将 ChromeDriver 降级到 ChromeDriver v73.0.3683.68 级.
• 将 Chrome 版本保持在 Chrome v73 级别.(根据 ChromeDriver v73.0.3683.68 发行说明)李>
• 清理你的项目工作区通过你的IDE和重建你的项目只需要依赖.
• 执行你的 @Test.
• 总是在 tearDown(){} 方法中调用 driver.quit() 来关闭 &优雅地销毁 WebDriver 和 Web Client 实例.
• Downgrade ChromeDriver to ChromeDriver v73.0.3683.68 level.
• Keep Chrome version at Chrome v73 level. (as per ChromeDriver v73.0.3683.68 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Execute your @Test.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
