为什么在Docker中运行ChromeDriver 2.31无法启动？

我有一个基于ubuntu:xenial的Docker容器。 当我尝试运行selenium Chrome加载不断

 >>> from selenium import webdriver >>> from selenium.webdriver.chrome.options import Options >>> chrome_options = Options() >>> chrome_options.add_argument("--headless") >>> path_to_chromedriver = '/usr/local/bin/chromedriver' >>> browser = webdriver.Chrome(path_to_chromedriver, chrome_options=chrome_options) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/chrome/webdriver.py", line 69, in __init__ desired_capabilities=desired_capabilities) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 140, in __init__ self.start_session(desired_capabilities, browser_profile) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 229, in start_session response = self.execute(Command.NEW_SESSION, parameters) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 297, in execute self.error_handler.check_response(response) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed (Driver info: chromedriver=2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8),platform=Linux 4.10.0-32-generic x86_64) 

迄今为止的步骤

修复崩溃

 >>> from selenium import webdriver >>> browser = webdriver.Chrome() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/chrome/webdriver.py", line 62, in __init__ self.service.start() File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/common/service.py", line 96, in start self.assert_process_still_running() File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/common/service.py", line 109, in assert_process_still_running % (self.path, return_code) selenium.common.exceptions.WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: 127 

当我试图find的chromedriver的版本

 chromedriver --version 

我得到了共享库libnss3没有find的错误。 安装libnss3后 ，它工作。

所以行

 RUN apt-get install libnss3 

应该被添加到Dockerfile中。

修复'chrome binary not found'

安装Chrome。 通过pip安装chromedriver_installer是不够的。

 RUN apt-get install wget RUN wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb RUN dpkg -i google-chrome-stable_current_amd64.deb; apt-get -fy install

您正在尝试创build自定义图像，当标准图像已经可用时。 你应该使用selenium/chrome-standalone

 docker run -d -p 4444:4444 selenium/standalone-chrom 

然后在你的代码中启动一个RemoteWebdriver

 from selenium import webdriver from selenium.webdriver.common.desired_capabilities import DesiredCapabilities driver = webdriver.Remote(desired_capabilities=DesiredCapabilities.CHROME)
