要注意chromedriver的版本号，我这边最新的稳定版chrome是66，所以要用2.38的chromedriver
下面是测试代码,seleuium,上面的安装的代码我没加放requirements.txt里了。

import time

from selenium import  webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')

driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("https://www.baidu.com")

time.sleep(4)

print(driver.find_element_by_id("lg"))
driver.close()

这边因为是root用户，要加--no-sandbox，不然会报错
