如何将 Homebrew 恢复到以前的状态? [英] How to get back Homebrew to previous state?

问题描述

我从文件夹 /usr/local/Homebrew/Library/Taps/中删除了一些 .rb 文件(cassandra.rb、[e-mail] 和 [e-mail])homebrew/homebrew-core/Formula/ 来自 mac 系统.我想找回那些 .rb 文件.
我以为 brew upgrade 会把那些删除的 .rb 文件还给我.但是他们仍然失踪.那些 .rb 文件对我安装软件包很重要.
brew install cassandra 给出

I deleted some of .rb files(cassandra.rb,[e-mail] and [e-mail]) from folder /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/ from mac system.I want back those .rb files.
I thought brew upgrade will give me back those deleted .rb files back.But they are still missing. Those .rb files are important for me to install packages.
brew install cassandra gives

Updating Homebrew...
Error: No available formula with the name "cassandra" 
==> Searching for a previously deleted formula...
cassandra was deleted from homebrew/core in commit d20fe73:
  cassandra: update 3.10_1 bottle.

To show the formula before removal run:
  git -C "$(brew --repo homebrew/core)" show d20fe73^:Formula/cassandra.rb

If you still use this formula consider creating your own tap:

请问我需要解决方案如何取回这些 .rb 文件?"或安装 cassandra 的任何其他替代方法".

Please I need solution "how to get back these .rb files?" or "any other alternative way to install cassandra".
