文件找不到错误，同时使用硒设置Chromedriver

Question

我正在尝试在Jupyter笔记本中使用Selenium设置Chromedriver。我还在chromedriver所在的Windows 10系统中设置了环境变量.exe但我仍然得到以下显示的错误。

这是我的代码：

# Import Libraries
import pandas as pd
import selenium
import os
from selenium import webdriver
chrome_path = r"C:UsersKlsinghDesktopchromedriver.exe"
wd = webdriver.Chrome()
wd.get(url)

下面是我得到的错误，已经尝试了几种方法，但仍然无法解决。

我正在尝试在不是我的桌面或 IDE 上的在线服务器上执行上述代码。 请帮忙。

谢谢 库玛

Answer 1

当您使用原始开关时，即r您需要将 WebDriver 变体的绝对路径括在单引号内，即'...'并通过密钥executable_path调用webdriver.Chrome()时传递它，如下所示：

因此，实际上您的代码行将是：

chrome_path = r'C:UsersKlsinghDesktopchromedriver.exe'
wd = webdriver.Chrome(executable_path=chrome_path)

或者，您可以在一行中实现相同的目标，如下所示：

wd = webdriver.Chrome(executable_path=r'C:UsersKlsinghDesktopchromedriver.exe')

Answer 2

我不得不解决同样的问题，只是在桌面上解决了它。

如果您使用的是适用于 Linux 或类似内容的 Windows 子系统，请确保路径键入正确且可从操作系统访问。

例如，在WSL中，/mnt/c/users/documents而不是C：/users/documents。
