from selenium import webdriver
driverPath = "C:/Users/ajack/.spyder-py3/chromedriver.exe"
browser = webdriver.Chrome(driverPath)
print(type(browser))

出現了
ValueError: Timeout value connect was <object object at 0x000001E91A1B4950>, but it must be an int, float or None.
想請問應該是要怎麼解決?

ChromeDriver路徑是正確的

以下是完整的錯誤訊息

GPT:
如果 browser = webdriver.Chrome() 可以正常執行，通常是因為你的系統已經將 chromedriver 添加到環境變量（PATH）中，或者 chromedriver 已經在 Selenium 預設的搜尋路徑中。Selenium 在嘗試啟動 Chrome 瀏覽器時會自動找到 chromedriver 可執行文件。

想說我都沒加那個路徑！？

也許可行?

最佳解答

1.可能是下載的 chromedriver 支援版本和你的 chrome 版本不同
2.嘗試更新 selenium

題外話
我一開始也是用chrome來做爬蟲也是遇到很多問題(特別是找不到支援我chrome版本的driver)
還要把chrome降版本甚麼的也看到別人說chrome很吃資源
後來就改用Edge做了做的挺順利的供參

#WebDriver 測試
from selenium import webdriver

driver = webdriver.Edge()
print(type(driver))

# 打開網頁
driver.get('https://www.example.com/')

"後來就改用Edge做了做的挺順利的供參"
這句很重要..感謝!

感謝您提供的意見用Edge做真的比較順利!但作業要用chrome

這是我修改後的chrome程式，加兩行程式，就可以開啟了

from selenium import webdriver
from selenium.webdriver.chrome.service import Service

driverPath = "C:/Users/ajack/.spyder-py3/chromedriver.exe"
service = Service(driverPath)

browser = webdriver.Chrome(service=service)
print(type(browser))

個人覺得在selenium上使用Chrome的時候版本問題會很令人頭痛，如果怕麻煩其實我覺得firefox跟edge都是很好的選擇。

但如果還是很想用Chrome，分享一下方法

可以下載測試用的Chrome之後指定路徑，就可以固定版本不會受到電腦中的Chrome的更新影響
https://developer.chrome.com/blog/chrome-for-testing?hl=zh-tw

可以透過這個方式指定執行的Chrome路徑
附上selenium文件

chromeOptions = webdriver.ChromeOptions()
chromeOptions.binary_location = f"{driver_path}/chrome-linux64/chrome"
driver = webdriver.Chrome(executable_path=f"{driver_path}/chromedriver-linux64/chromedriver", options=chromeOptions)
