Linux上使用Python的Xvfb Selenium無頭Chrome

Question

我正在嘗試在python中使用硒無頭運行chrome。 我嘗試了xvfb-run -a python3 message.py而我收到此錯誤：

Traceback (most recent call last):
  File "message.py", line 388, in <module>
    initialize()
  File "message.py", line 54, in initialize
    driver = webdriver.Chrome(chrome_options = chrome_options)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/chrome/webdriver.py", line 75, in __init__
    desired_capabilities=desired_capabilities)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 154, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 243, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/webdriver.py", line 312, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/remote/errorhandler.py", line 237, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (Driver info: chromedriver=2.33.506178 (69ae10f91723897591ef1a3b465aa5d35011eb5e),platform=Linux 3.13.0-96-generic x86)

和initialize（）：

   chrome_options = webdriver.ChromeOptions()
   chrome_options.add_argument("--headless")
   chrome_options.add_argument("--no-sandbox")
   chrome_options.add_argument("--verbose")
   chrome_options.add_argument("--log-path=chrome.log")
   chrome_options.add_argument("window-size=1200x600")
   chrome_options.add_argument("user-data-dir=\\")
   driver = webdriver.Chrome(chrome_options = chrome_options)
   driver.get('http://google.com')

我在Linux32上使用Python 3.5和chromedriver 2.33.506178（Ubuntu作為不帶桌面的服務器）在裝有Linux Mint的另一台PC上測試了相同的代碼，一切正常。

希望你能幫我 ：）

在檢查了我實際的寫/讀/執行權利之后，我發現了我的錯誤。 嘗試使用root權限執行操作時，chromedriver無法加載。 更改chromedrivers權限后，現在一切正常。
