selenium 报错

1. selenium WebDriverException: Message: unknown error: DevToolsActivePort file doesn’t exis

解决办法：禁用sandbox

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)

2. session not created: This version of ChromeDriver only supports Chrome version 77

显示chrome与chromedriver的版本不一致

解决方案：下载版本一致的chromedriver
ChromeDriver下载地址：http://npm.taobao.org/mirrors/chromedriver/
