氦 package 找不到 Chrome 二進制文件

Question

我已經安裝了 selenium 和氦氣包，我在 Windows 10 64 Bit 上使用 pythom 3.8.3 並且在嘗試這些行時

from helium import *

url = 'https://www.moi.gov.kw/'
browser = start_chrome(url)

我得到了這個回溯

Answer 1

我用過這樣的線，問題就解決了。

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)
