问题描述
我已经安装了 selenium 和 helium 包，并且我在 Windows 10 64 位上使用 pythom 3.8.3 当尝试这些行时
from helium import *
url = 'https://www.moi.gov.kw/'
browser = start_chrome(url)
我得到了这个回溯

解决方法
我用过这样的线路，问题解决了。
from selenium.webdriver.chrome.options import Options
options = Options()
options.binary_location = "C:/Program Files/Google/Chrome/Application/chrome.exe"
browser = start_chrome(url,headless=False,options=options)
