使用 brew extract 安装先前版本的公式

Question

由于Subversion 1.13 Brew 公式的问题，我安装了该公式的旧版本：

brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/0c3d786402ad7d9dd5eb6907e3ed3f2525a0472d/Formula/subversion.rb

这给出了警告：

Warning: Calling Installation of subversion from a GitHub commit URL is deprecated! Use 'brew extract subversion' to stable tap on GitHub instead.

建议与此提示相同。

现在，我想正确使用brew extract subversion而不是使用已弃用的提交 URL。我想在某些计算机上安装 Subversion 1.13_5，但 Subversion 1.14 是最新的公式。

我需要做的是这样的：brew extract --version 1.13.0_5 subversion <tap>。

我理解这一点的方式我应该：

1. 为我的版本化公式创建一个空存储库
2. 添加存储库作为点击并初始化它
3. 提取版本化公式
4. 提交并推动公式？

我创建了一个空的存储库，然后：

$ brew tap rjollos/homebrew-versioned
Cloning into '/usr/local/Homebrew/Library/Taps/rjollos/homebrew-versioned'...
warning: You appear to have cloned an empty repository.
Tapped (16 files, 22.2KB).
$ brew tap-new rjollos/homebrew-versioned
==> Created rjollos/versioned
/usr/local/Homebrew/Library/Taps/rjollos/homebrew-versioned
$ brew extract --version '1.13.0_5' subversion rjollos/homebrew-versioned
==> Searching repository history
Warning: Calling 'devel' blocks in formulae is deprecated! Use 'head' blocks or @-versioned formulae instead.
Please report this issue to the homebrew/core tap (not Homebrew/brew or Homebrew/core), or even better, submit a PR to fix it:
  /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/subversion.rb:16

Warning: Calling 'devel' blocks ... (repeats about a dozen times)

Error: subversion: undefined method `sha1' for #<SoftwareSpec:0x00007fceaf144490>

我想我做错了几件事，但主要是我不确定为什么brew extract不起作用。另外，有没有更好的方法来创建新的存储库并用模板文件填充它以进行新的点击？

$ brew --version
Homebrew 2.4.4-19-ge09802b
Homebrew/homebrew-core (git revision 5ee797; last commit 2020-07-07)
Homebrew/homebrew-cask (git revision 837ac; last commit 2020-07-08)

Answer 1

Taps 可以在没有实际 github 存储库的情况下在本地创建。这是一般示例：

TAP=...     # <org>/<repo>, for example "my-org/homebrew-old"
MODULE=...  # name of module you want to install, e.g. "hugo"
VERS=...    # version of $MODULE you want to install, e.g., "0.80.0"
brew tap-new $TAP
brew extract --version $VERS $MODULE $TAP
brew install $TAP/$MODULE@$VERS

仍然不确定这是创建新水龙头的最佳方式。我homebrew-repo在我的 GitHub 上创建，然后添加了水龙头，然后使用tap-new.

$ TAP=rjollos/homebrew-repo
$ TAP_PATH=$(brew --repository)/Library/Taps/$TAP

$ brew tap $TAP
==> Tapping rjollos/repo
Cloning into '/usr/local/Homebrew/Library/Taps/rjollos/homebrew-repo'...
warning: You appear to have cloned an empty repository.
Tapped (16 files, 22.2KB).

$ brew tap-new $TAP
==> Created rjollos/repo
/usr/local/Homebrew/Library/Taps/rjollos/homebrew-repo

$ cd $TAP_PATH

$ git add .

$ git commit -m "Initialized with template files"
[master (root-commit) c7c4bed] Initialized with template files

 create mode 100644 README.md

$ git remote -v
origin  https://github.com/rjollos/homebrew-repo (fetch)
origin  https://github.com/rjollos/homebrew-repo (push)

提取版本化公式：

$ brew extract --version 1.13.0 subversion $TAP
==> Searching repository history
==> Writing formula for subversion from revision dab5452 to:
/usr/local/Homebrew/Library/Taps/rjollos/homebrew-repo/Formula/subversion@1.13.0.rb

添加公式：

$ cd $TAP_PATH
$ git add Formula
$ git commit -m "Add Subversion 1.13 formula"
 1 file changed, 203 insertions(+)
 create mode 100644 Formula/subversion@1.13.0.rb
