解决：DevToolsActivePort file doesn't exist的问题
解决办法：直接把sandbox禁用了。
需要导入：
from selenium.webdriver.chrome.options import Options
chrome_options.add_argument(’–no-sandbox’)# “–no - sandbox”参数是让Chrome在root权限下跑
chrome_options.add_argument(’–disable-dev-shm-usage’)
chrome_options.add_argument(’–headless’) # “–headless”参数是不用打开图形界面（#浏览器不提供可视化页面. linux下如果系统不支持可视化不加这条会启动失败）
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)
实际应用中的代码是：
chrome_options = Options()
chrome_options.add_argument(’–no-sandbox’)
chrome_options.add_argument(’–disable-dev-shm-usage’)
chrome_options.add_argument(’–headless’)
self.driver = webdriver.Chrome(chrome_options=chrome_options)
self.url = “http://192.0.4.79/#/login”
self.driver.implicitly_wait(5)
报错信息如下：
