我正在尝试在我的 imac 上使用 Homebrew 在终端中下载 Hydra，但它给了我这个错误：
You must `brew link makedepend` before hydra can be installed
当我运行时：
brew link makedepend
它说：
Error: Could not symlink .
/usr/local/opt is not writable.
如果我使用 sudo 它会说：
Running Homebrew as root is extremely dangerous and no longer supported.
As Homebrew does not drop privileges on installation you would be giving all
build scripts full access to your system.
谁能帮我谢谢！
