我正在尝试学习 python 网络抓取,但我无法让 selenium 与任一浏览器一起使用。
from selenium import webdriver
browser = webdriver.Firefox()
这是我所有的代码,我得到这个是为了一个错误。

我已经尝试了所有我能在互联网上找到的方法,包括将路径添加到代码中
from selenium import webdriver
browser = webdriver.Firefox("C:\Program Files (x86)\Mozilla Firefox\firefox.exe")
将它添加到我的环境变量中的 PATH 中。我似乎无法弄清楚...
最佳答案
对于 Firefox 和 Chrome,您现在需要下载 geckodriver/chromedriver .这些驱动程序是您安装的浏览器和 selenium 之间进行通信所必需的。所以你需要:
- 为 python 安装 selenium (
pip install selenium
) - 下载drivers适用于您要使用的浏览器(chromedriver、geckodriver、operadriver 等)
- 在您的系统上安装您想使用的浏览器(可能已经有了)
现在您可以按照 anwser 中的说明将 geckodriver 添加到您的路径中.或者您可以像这样直接在您的代码中设置它:
家:
driver = webdriver.Chrome(executable_path='/path/to/chromedriver.exe')
火狐:
driver = webdriver.Firefox(executable_path='/opt/geckoDriver/geckodriver.exe')
关于python - selenium 不适用于 Firefox 或 Chrome,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/40437226/
