Answer 1

这可能是与权限相关的错误。

试一试

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

或者，如果您只需要在git-core路径上使用它，

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

可能就够了。

然后运行

brew link git

再来一次。

Answer 2

也许您之前使用sudo安装了一些应用程序，因此字典/usr/local/share/和/usr/local/lib的所有者变成了root

运行：

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

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

然后运行：

brew link git

Answer 3

在更改权限之前，我会：：

选项1:尝试卸载brew

1)保存brew软件包列表：

brew list > my_packages.txt

2)然后是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)重新安装所有包：

brew install $(< my_packages.txt )

选项2:

如果这不起作用，请尝试运行：

brew doctor

使用以下命令检查是否可以删除错误：

brew prune
