我开始使用子树,但现在结束了混乱。谷歌和手册页没有帮助,我可以找到如何解决这个错误。有人有主意吗?

错误:

➜ git subtree split -P gitkraken --rejoin
cache for 12d7b0ee9414ebd0414070d22fb40db7446badd9 already exists!

示例来从外部复制它。

mkdir test
cd test
git init
touch readme.md
git config --global user.email "you@example.com"
git config --global user.name "Your Name"
git add readme.md
git commit -m "add readme"
git subtree add --prefix gitkraken "aur@aur.archlinux.org:gitkraken.git" master
git subtree split -P "gitkraken" --rejoin

目前,在我的repo中,我将文件夹切换到gitkraken-aur,因此它暂时再次工作。
从第一个答案开始尝试删除子树文件夹。

test on  main [?]
➜ rm -rf .git/subtree-cache

test on  main [?]
➜ git subtree split -P "gitkraken" --rejoin

cache for 12d7b0ee9414ebd0414070d22fb40db7446badd9 already exists!

test on  main [?]
➜ git subtree pull -P gitkraken "aur@aur.archlinux.org:gitkraken.git" master -m "Merge subbtree gitkraken"

更多调试信息以尝试一个。

你需要通过删除.git/subtree-cache文件夹来清除子树缓存,你可以尝试在该文件夹中搜索12d7b0ee9414ebd0414070d22fb40db7446badd9文件并删除它。
然后再试一次执行你的命令。
我能够重现和修复的方式,答案是通过逆向工程的代码导致的错误:https://github.com/git/git/blob/master/contrib/subtree/git-subtree.sh#L329

我也遇到过同样的问题,花了很多时间去解决。
我的同事也有同样的问题,在重新安装了几次git之后,问题解决了,我问他使用的是哪个版本。
将git版本降级到2.30.2后,“缓存***exist”消息仍然出现,但“子树推送”操作成功运行
在我的例子中,有问题的git版本是2.35.2

我不知道这对调试这个问题是否有帮助,但我今天仍然在git 2.39.2版本中得到它。
我达到这一点的方法可能是添加git子树,然后删除它们,再重新添加相同的子树。
我的感觉是,如果历史中的某个地方有不止一个子树add,就会发生这种情况:

git subtree push -d --prefix commerce/packages/xx/xx-component-phpmd-config xx-component-phpmd-config main

command: {push}
quiet: {}
dir: {commerce/packages/xx/xx-component-phpmd-config}
opts: {xx-component-phpmd-config main}

git push using:  xx-component-phpmd-config main
Splitting commerce/packages/xx/xx-component-phpmd-config...
Using cachedir: /Users/antonevers/web/xx/xx-monorepo/.git/subtree-cache/12575
Looking for prior splits...

    Prior: 5cc22cd76dc2ddd4fdaf05445ebee23c4705eee1 -> ede24f61adf6ce0b1a7853c334470a88f27c7bef
  Main is: '2b41e165071909200abd959fc609aea4c97bcd82'
    Prior: 2b41e165071909200abd959fc609aea4c97bcd82 -> ede24f61adf6ce0b1a7853c334470a88f27c7bef
fatal: cache for ede24f61adf6ce0b1a7853c334470a88f27c7bef already exists!

我已经解决了这个问题,在添加子树之前先从历史中的一部分分支出来,然后完全重新开始,这样就绕过了历史中子树被多次添加到同一路径的点。
