Question

长话短说，我正在创建一个不和谐机器人，我需要youtube-dl才能这样做。当我在终端上安装它时，我使用了命令

pip install youtube-dl

我得到了这个

我真的不知道如何制作这个或天气，或者不是它在高山脉中的pip命令本身就是一个错误。任何帮助，将不胜感激。谢谢！

Answer 1

您正在获得权限被拒绝，因为当前用户没有必要的权限，因此请使用sudo以及您的命令，如下所示：

sudo pip install youtube-dl

或使用root用户运行终端并运行命令。

Answer 2

我建议您不更改系统Python，而是使用homebrew安装Python，然后安装youtube-dl：

brew install python
brew install youtube-dl

我在macOS High Sierra上通过pip命令安装youtube-dl时遇到错误
