硒腳本不在python中運行

Question

嘗試執行

from selenium import webdriver

browser=webdriver.Chrome()

browser.get('http://www.google.com')

但不執行並引發錯誤

=RESTART: C:\Users\Phani\AppData\Local\Programs\Python\Python37-32\drive.py =

在處理上述異常的過程中，又出現了一個異常：

    browser=webdriver.Chrome()

使用 pip install 正確安裝 selenium

請幫忙！！

Answer 1

這不起作用，因為您沒有提供 chrome 驅動程序的路徑。 WebDriver不知道chromedriver路徑在哪里。

driver = webdriver.Chrome("path of the chrome driver Chromedriver.exe")

例如：

from selenium import webdriver
driver = webdriver.Chrome("d:/chromedriver/Chromedriver.exe")
driver.get("https://www.google.com")

Answer 2

為此，您可以嘗試使用 Firefox：

首先從這里下載 Geckodriver： https ://github.com/mozilla/geckodriver/releases/tag/v0.24.0

from selenium import webdriver
fox = webdriver.Firefox(executable_path='/path/to/downloaded/gecko/driver')
fox.get("https://www.google.com")

google chrome也可以這樣做：

您可以從這里下載 chrome 驅動程序：

https://sites.google.com/a/chromium.org/chromedriver/home

無需設置 PATH 變量。

Answer 3

我剛剛解決了這個問題。 您需要下載 Google Chrome 的更新版本。 例如，我的舊版本是 96，但現在是 101。就是這樣。
