尝试使用selenium打开网页但得到错误

Question

我写了这个简单的代码：

from selenium import webdriver
webdriver.Chrome().get('www.google.co.in')

但我发现了一个错误：

Traceback (most recent call last):
  File "C:\Users\user\PycharmProjects\WebAutomation\venv\lib\site-packages\selenium\webdriver\common\service.py", line 71, in start
    self.process = subprocess.Popen(cmd, env=self.env,
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\subprocess.py", line 966, in __init__
    self._execute_child(args, executable, preexec_fn, close_fds,
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\subprocess.py", line 1435, in _execute_child
    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

  File "C:\Users\user\PycharmProjects\WebAutomation\venv\Automation.py", line 2, in <module>
    webdriver.Chrome().get('www.google.co.in')

谁来帮帮我。我是初学者，请详细解释/指导(我不知道复杂的概念)

Answer 1

您将需要额外的Selenium-ChromeDriver.exe！最后一行错误告诉您。

selenium.common.exceptions.WebDriverException:消息：“

驱动程序”可执行文件需要在路径中。请参阅https://chromedriver.chromium.org/home

驱动程序本身将从您的程序启动，并将保存您的程序和浏览器铬本身之间的绑定。

driver.exe可以很容易地放置在程序启动路径中(我建议在第一步中这样做)，也可以放置到任何您想要的位置，但是您必须定义driver.exe路径的特殊变量。

您可以在这个链接后面获得driver.exe：

主页：https://chromedriver.chromium.org/getting-started

下载网页：https://chromedriver.chromium.org/downloads

请确保您的浏览器版本与驱动程序版本匹配.
