Message:Unable to obtain chromedriver using Selenium Manager

问题

我在我的Jupyter笔记本上尝试编写这段代码,但出现了错误。我的目标是进行网络爬虫。

driver = webdriver.Chrome(ChromeDriverManager().install())

在此输入图像描述

我还使用pip安装了selenium和webdriver-manager。

英文:

I've tried writing this code on my jupyter notebook, and it shows me the error. My objective is to carry out web scrapping.

driver = webdriver.Chrome(ChromeDriverManager().install())

enter image description here

I've also installed selenium using pip and webdriver-manager using pip as well.

The output of ChromeDriverManager().install() is an executable_path to the driver, but executable_path was removed in selenium 4.10.0. That's why you're seeing the error after passing the value into webdriver.Chrome(). Here are the changes: Link

Note that executable_path was removed. If you want to pass in an executable_path, you'll have to use the service arg now. (service=Service(executable_path='./chromedriver')) But Selenium Manager is now fully included with selenium 4.10.0, so this is all you need:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service

service = Service()
options = webdriver.ChromeOptions()
driver = webdriver.Chrome(service=service, options=options)
# ...
driver.quit()

If the driver isn't found on your system PATH, Selenium Manager will automatically download it for you.

尝试删除 ChromeDriverManager,如果您的 Selenium 版本为 v4.6.0 或更高,则不需要它。

将下面的代码更改为:

driver = webdriver.Chrome()

Can you try by removing the ChromeDriverManager, you don't need it if your selenium version is v4.6.0 or above.

Change below:

driver = webdriver.Chrome(ChromeDriverManager().install())

Selenium Manager

Selenium Manager 是一个新工具,可以帮助获取所需的浏览器驱动程序,以便在不需要其他配置的情况下运行 Selenium。Selenium Manager 的 Beta 1 版本会为 Chrome、Firefox 和 Edge 配置浏览器驱动程序,如果它们不在 PATH 中。因此,要使用 Selenium 4.6 及更高版本运行 Selenium 测试,只需安装 [tag:google-chrome]、[tag:firefox] 或 [tag:microsoft-edge] 即可。如果已经安装了浏览器驱动程序,此功能将被完全忽略。


Current Status

Selenium Manager 工具目前仍处于测试阶段,Selenium 正逐步增加对此功能的支持。当前的实现是一个 fall-back 选项,这意味着只有在否则会执行失败的情况下才会使用它。只要您在适当的 Service 类中指定了驱动程序的位置(或者在 Java 中使用 System Properties),Selenium Manager 将不会被使用。


Solution

有两种不同的方法如下:

  • 您完全可以避免使用 webdriver-manager,您的有效代码块将是:

    driver = webdriver.Chrome()
    
  • 要继续使用 webdriver-manager,您必须使用 Service 类,您的有效代码块将是:

    driver = webdriver.Chrome(service=ChromeDriverManager().install())
    
英文:

Selenium Manager

Selenium Manager is the new tool that helps to get the required browser drivers to run Selenium out of the box. Beta 1 of Selenium Manager configures the browser drivers for Chrome, Firefox, and Edge if they are not present on the PATH. So To run a Selenium test with Selenium 4.6 and onwards you just need to have [tag:google-chrome], [tag:firefox] or [tag:microsoft-edge] installed. If you already have browser drivers installed, this feature will be ignored completely.


Current Status

Selenium Manager tool is still in beta phase and Selenium is gradually adding support for this feature. The current implementation is a fall-back option, which means it should only get used if the code execution would otherwise fail. So long as you specify the location of the driver in the appropriate Service class (or using System Properties in Java), the Selenium Manager will not be used.


Solution

There are 2 different approaches as follows:

  • You can totally avoid webdriver-manager and your effective code block will be:

    driver = webdriver.Chrome()
    
  • To keep using the webdriver-manager you have to use the Service class and your effective code block will be:

    driver = webdriver.Chrome(service=ChromeDriverManager().install())
