将Silenium与Chrome的网络驱动程序一起使用并获得"Permission denied"或"No such file or directory"(Mac)

Question

我正在尝试将Python与selenium一起使用以自动从网站下载文件，但是当我尝试调用chromeDriver时，我收到错误。我尝试了两种不同的方法，但没有成功。关于如何修复一种或另一种方式工作的任何想法？

方式1：

from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages')

这将产生错误：

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 72, in start

raise WebDriverException(

方式 2

from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'/Chrome/chromedriver.exe')

这将产生错误：

Answer 1

当我尝试在 Linux 服务器上运行驱动程序时，我遇到了同样的问题。 用

chmod +x chromedriver

为我做了这个把戏。 (感谢@Thomas Q对此提示的评论！

Answer 2

您需要为您的系统安装适当的 chromedriver 。在您的情况下，您将下载chromedriver_mac64.zip。你可以在这里得到它。然后你需要从zip中提取chromedriver文件，并将其放在与python脚本相同的目录中，并使用相对路径

from selenium import webdriver driver = webdriver.Chrome(executable_path='./chromedriver')

如果需要，还可以使用文件的绝对路径。如果您要将文件拖到桌面上，它看起来像这样：

from selenium import webdriver driver = webdriver.Chrome(executable_path='/Users/YOUR_USERNAME/Desktop/chromedriver')

Answer 3

我在PermissionError: [Errno 13] Permission denied:和科里一样遇到了完全相同的问题，当我删除Chromedriver的任何副本时，我下载并解压缩了该文件并将其放在我的用户目录中，它只是工作。
