前言：繼裝完xcode-select 和command line 又報錯
報錯信息：
You are using macOS 11.4.
We do not provide support for this pre-release version.
You will encounter build failures with some formulae.
Please create pull requests instead of asking for help on Homebrew's GitHub,
Discourse, Twitter or IRC. You are responsible for resolving any issues you
experience while you are running this pre-release version
修復方式：執(zhí)行以下這句命令
cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update
可能是由于好多庫沒更新我的花費很長時間
使用命令等待很長時間后顯示如下信息

OK ,解決豁遭。
