Question

我正在尝试使用Jupyter笔记本电脑中的硒设置Chromedriver。我还在chromedriver.exe所在的Windows 10系统中设置了环境变量，但仍然出现以下显示的错误。

这是我的代码：

# Import Libraries
import pandas as pd
import selenium
import os
from selenium import webdriver
chrome_path = r"C:\Users\Klsingh\Desktop\chromedriver.exe"

wd = webdriver.Chrome()
wd.get(url)

以下是我得到的错误，尝试了几种方法，但仍无法解决。

During handling of the above exception, another exception occurred:

WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

我正在尝试在不在台式机或IDE上的在线服务器上执行上述代码。请帮忙。

谢谢，库马尔

Answer 1

使用 raw 开关（即 r ）时，您需要封装{{3}的绝对路径 } 单引号中的变体，即'...'，并在通过 Key webdriver.Chrome() 调用executable_path时传递如下：

因此，有效的代码行将是：

chrome_path = r'C:\Users\Klsingh\Desktop\chromedriver.exe'

wd = webdriver.Chrome(executable_path=chrome_path)

或者，您也可以在一行中实现以下目标：

wd = webdriver.Chrome(executable_path=r'C:\Users\Klsingh\Desktop\chromedriver.exe')

Answer 2

我不得不遇到同样的问题，只是在台式机上解决了这个问题。

如果您将Windows子系统用于Linux或类似的操作系统，请确保路径键入正确且可从OS访问。

例如，在WSL中，以/ mnt / c / users / documents代替C：/ users / documents

使用硒设置Chromedriver时出现文件未找到错误
