下载hydra时出现brew错误(在安装hydra之前，必须‘brew link must’)

Question

我尝试在我的imac上使用Homebrew在终端中下载Hydra，但它给出了这个错误：

You must `brew link makedepend` before hydra can be installed

当我跑的时候：

brew link makedepend

上面写着：

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.

有人能帮帮我吗?谢谢！

首先运行brew update，然后运行brew doctor。它可能会要求您在/usr/local/上使用chmod。请按照其说明进行操作。
