使用brew在MacOS上安装特定的git版本

Question

我正在尝试从brew安装较旧的git版本。

我已经安装了git 2.33.1

▶ brew info git
git: stable 2.33.0 (bottled), HEAD
Distributed revision control system
https://git-scm.com
/usr/local/Cellar/git/2.33.0_1 (1,508 files, 42MB) *
  Poured from bottle on 2021-10-08 at 12:06:00
From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/git.rb
License: GPL-2.0-only
==> Dependencies
Required: gettext ✔, pcre2 ✔
==> Options
--HEAD
    Install HEAD version
==> Caveats
The Tcl/Tk GUIs (e.g. gitk, git-gui) are now in the `git-gui` formula.

zsh completions and functions have been installed to:
  /usr/local/share/zsh/site-functions

Emacs Lisp files have been installed to:
  /usr/local/share/emacs/site-lisp/git
==> Analytics
install: 198,758 (30 days), 658,960 (90 days), 2,607,801 (365 days)
install-on-request: 194,065 (30 days), 644,952 (90 days), 2,558,858 (365 days)
build-error: 0 (30 days)

我需要(出于某些故障排除目的)一个旧版本，即2.25.1

为什么看起来没有其他(更老的)版本可用？

▶ brew install git@2.25.1
Warning: No available formula or cask with the name "git@2.25.1".
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

我也尝试过this更老的话题的建议，但没有任何运气。

安装某些公式的特定版本的受支持方法是查看是否有可用的版本化公式(例如gcc@7)。如果您正在寻找的版本不可用，请考虑使用brew extract。

运行以下命令以创建名为$USER/local-tap的tap，将git 2.25.1解压缩到tap中，然后安装：

brew tap-new --no-git $USER/local-tap
brew extract --version=2.25.1 git $USER/local-tap
brew install git@2.25.1
/usr/local/opt/git@2.25.1/bin/git --version
