The above answers were helpful. I would just add that if you're running Selenium from a development environment, in my case a Jupyter Notebook, and this is the issue, you're likely to see a PermissionError: [Errno 13] Permission denied error. There are other causes for this error, but it can be that macOS Catalina is blocking chromedriver from running for security reasons. Following the approaches above, I ran it from the command line and then was able to open it from Jupyter using driver = webdriver.Chrome('path/to/chromedriver).

解决这个问题有两个步骤:

使用- cd /usr/local/bin命令进入该路径。这是你将看到你的chromedriver安装的地方。 当进入bin目录时，执行此命令- xattr -d com.apple.quarantine chromedriver。

就这些。这对我来说很管用。

这是一个许可问题…… 升级chrome后，这个错误显示，所以我遵循下面提到的步骤，它在我的系统工作。

系统设置 安全与隐私 进入“常规”选项卡 允许从以下地方下载应用程序: 选择App Store和已识别的开发商 单击锁进行更改。 输入系统密码 点击“无论如何打开”来确认你要打开或安装应用程序的意图。

快速解决方案

开放的仪 导航到chromedriver文件所在的位置 右键单击chromedriver文件并选择打开

在此之后，脚本应该可以正常工作。

打开终端，进入下载chromedriver的路径。 执行xattr -d com.apple.quarantine chromedriver
