标签： git macos homebrew

【解决方案1】：

这可能是与权限有关的错误。

试试

sudo chown -R $(whoami) /usr/local/share/

或者，如果你只在 git-core 路径上需要这个，

sudo chown -R $(whoami) /usr/local/share/git-core

可能就够了。

然后运行

brew link git

再次。

【讨论】：

谢谢，但这也无济于事....终端告诉我：Christophs-MacBook-2:~ AWChristoph$ brew link git Error: No such keg: /usr/local/Cellar /git
那里似乎是同样的问题。做一个sudo chown -R $(whoami) /usr/local/Cellar/。
@AWChristoph：这有帮助吗？
@AWChristoph：我认为你有点忽略了我们使用 chown -R 所做的事情。每次您偶然发现新的 permission denied 消息时，那是因为当前正在运行 brew 命令的用户没有写入这些目录的权限。话虽如此，对于您发布的这条最新消息，您需要执行chown -R $(whoami) /usr/local/lib/perl5/。但也许只做sudo brew link git 会更容易。不过，通常不建议这样做。
我正在运行 ZSH，对我来说是：sudo chown -R $(whoami) /usr/local/share/zsh/site-functions。

【解决方案2】：

也许你之前使用sudo安装了一些应用程序，所以字典的所有者/usr/local/share/和/usr/local/lib变成了root

运行：

sudo chown -R $(whoami) /usr/local/share/

sudo chown -R $(whoami) /usr/local/lib

然后运行：

brew link git

【讨论】：

他告诉我：没有这样的小桶：/usr/local/Cellar/git

【解决方案3】：

在更改权限之前，我会：

选项 1：尝试卸载 brew

1 ) 保存您的 brew 软件包列表：

brew list > my_packages.txt

2) 然后uninstall brew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

3)Re-install brew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

4 ) 重新安装所有软件包：

brew install $(< my_packages.txt )

选项 2：

如果这不起作用，请尝试运行：

brew doctor

检查是否可以使用以下方法修剪错误：

brew prune
