Chrome headless mode isn't working

[shengyilu]

I followed the instruction to edit settings.py as :

SELENIUM_DRIVER_NAME = 'chrome'
SELENIUM_DRIVER_EXECUTABLE_PATH = '/Users/****/chromedriver'
SELENIUM_DRIVER_ARGUMENTS=['--headless']

However, the Chrome will be launched every time I run the spider.
BTW, with only Selenium, headless mode was working correctly:
options = Options()
options.add_argument("--headless")
driver = webdriver.Chrome(service = Service(ChromeDriverManager().install()), options = options)

Does anyone face the same problem? Need some help.

from shutil import which
ChromeDriverManager().install() also downloads and returns path. so this was working for me

SELENIUM_DRIVER_NAME = 'chrome'
SELENIUM_DRIVER_EXECUTABLE_PATH = which(ChromeDriverManager().install())
SELENIUM_DRIVER_ARGUMENTS=['--headless']
