報錯
環境：
CentOS7.5
Python 3.6.5
chromedriver_linux64 2.40
Selenium
Google Chrome 67
使用Selenium和Chrome，報如下錯誤：

File "/usr/local/anaconda3/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist
  (Driver info: chromedriver=2.40.565383 (76257d1ab79276b2d53ee976b2c3e3b9f335cde7),platform=Linux 3.10.0-862.3.2.el7.x86_64 x86_64)
 

解決辦法
直接把sandbox禁用了。

from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless')
options.add_argument('--no-sandbox')
# options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome(executable_path="/root/chromedriver",
chrome_options=options)
