我正在嘗試使用 python 制作一個網路爬蟲。在我的win10系統上，這作業正常。但是當我部署到 Heroku 時，出現以下錯誤。我不知道為什么它不起作用。
代碼 ：
from selenium import webdriver
import os
URL = "https://www.google.com" #URL
options = webdriver.ChromeOptions()
options.binary_location = os.environ.get("GOOGLE_CHROME_BIN")
options.add_argument("--no-sandbox")
options.add_argument("--disable-gpu")
options.add_argument("--headless")
driver = webdriver.Chrome(executable_path=os.environ.get("CHROMEDRIVER_PATH"), options=options)
driver.get(URL)
錯誤 ：

解決方案
隨著selenium4密鑰executable_path被棄用，您必須使用Service()類的實體和ChromeDriverManager().install()命令，如下所示。
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
options = Options()
options.add_argument("start-maximized")
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)
driver.get("https://www.google.com")
