在 macOS High Sierra 上通过 pip 命令安装 youtube-dl 时出现错误

Question

长话短说，我正在创建一个不和谐的机器人，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

我明白了

Collecting youtube-dl

我真的不知道这是怎么回事或天气与否，这是 High Sierra 中 pip 命令本身的错误。任何帮助，将不胜感激。谢谢！

Answer 1

您的权限被拒绝，因为当前用户没有所需的权限，因此请使用 sudo 以及您的命令，如下所示：

sudo pip install youtube-dl

或运行 root 用户终端和运行您的命令。

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

brew install python
brew install youtube-dl
