具体有什么用吾亦不知道。有时提示这个错误，有可能是别的错误引起的。

• 具体错误

Error: You are using macOS 10.13.
We (and Apple) do not provide support for this old version.
You will encounter build failures with some formulae.
Please create pull requests instead of asking for help on Homebrew's GitHub,
Twitter or any other official channels. You are responsible for resolving
any issues you experience while you are running this
old version.
