我试图在Ubuntu 22.04上运行这个简单的Python webbot示例:
from webbot import Browser
web = Browser()
web.go_to('google.com')
web.type('hello its me') # or web.press(web.Key.SHIFT + 'hello its me')
web.press(web.Key.ENTER)
web.go_back()
web.click('Sign in')
web.type('mymail@gmail.com' , into='Email')
web.click('NEXT' , tag='span')
web.type('mypassword' , into='Password' , id='passwordFieldId')
web.click('NEXT' , tag='span') # you are logged in . woohoooo
然而，当我使用Python3运行示例时，我得到这个错误:
web = Browser()

self.driver = webdriver.Chrome(executable_path=driverpath, options=options)

我安装Chrome使用:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo apt install ./google-chrome-stable_current_amd64.deb
如何解决这个问题?
我对这个很陌生，我只是想登录一个网站，不管用什么浏览器。
我用谷歌搜索如何使用Firefox，但是库的名字使搜索变得困难。
您使用的是什么版本的selenium ?当你使用高于3.141.0的硒版本时，我看到了webbot的问题。如果你有更高的版本，你将不得不用这个替换它，然后尝试运行你的脚本。
