Jupyter Notebook selenium webdriver webdriver 不工作/打开

Question

我安装了te selenium模块，进入coe打开webbrowser，但是报错，webbrowser打不开。 实际上访问我的浏览器不起作用。 我是 Python 新手，正在学习在线课程。 前两行是我的输入，下面是错误。 有人可以帮忙吗？

from selenium import webdriver
browser=webdriver.Firefox()

Answer 1

将可执行路径设置为geckodriver.exe

例如，

from selenium import webdriver
driver = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')

如果您获得错误的权限，请尝试从路径中删除 [r']，只需“excecutable_path='path\\to\\your'diretory'”
