使用pip install正确安装了selenium
请帮忙!!
这不起作用,因为你没有提供chrome驱动程序的路径.WebDriver
不知道chromedriver
路径在哪里。
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")
您可以为此目的尝试Firefox:
首先从这里下载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")
使用google chrome
也可以这样做:
你可以从这里下载chrome驱动程序:
https://sites.google.com/a/chromium.org/chromedriver/home
无需设置PATH变量。
