我有一个项目,在lib/three20有一个子模块
我的.gitmodule文件是这样的:
[submodule "lib/three20"]
path = lib/three20
url = git://github.com/facebook/three20.git
我克隆了这个在过去没有错误,(git子模块init紧随git子模块更新),它已经工作了一段时间。
我试图克隆这个到一个新的机器,现在我在git子模块init上得到这个错误:
No submodule mapping found in .gitmodules for path 'Classes/Support/Three20'
这个路径只是Xcode中的一个空文件夹,我用它来存放来自另一个目录的项目。它不是.gitmodules文件的一部分,所以我不知道它从哪里得到这个路径。
什么好主意吗?
有个问题。有一段时间,我尝试了删除路径的建议,git删除路径,删除.gitmodules,从.git/config中删除条目,重新添加子模块,然后提交并推送更改。这是令人困惑的,因为当我做“git commit -a”时,它看起来没有变化,所以我试着只推删除,然后推读取,使它看起来像一个变化。
After a while I noticed by accident that after removing everything, if I ran "git submodule update --init", it had a message about a specific name that git should no longer have had any reference to: the name of the repository the submodule was linking to, not the path name it was checking it out to. Grepping revealed that this reference was in .git/index. So I ran "git rm --cached repo-name" and then readded the module. When I committed this time, the commit message included a change that it was deleting this unexpected object. After that it works fine.
不知道发生了什么,我猜有人误用了git子模块命令,可能颠倒了参数。甚至可能是我……希望这能帮助到一些人!
场景:将子模块从目录dirA-xxx更改为另一个目录dirB-xxx
move the dirA-xxx to dirB-xxx
modify entry in .gitmodules to use dirB-xxx
modify entry in .git/config to use dirB-xxx
modify .git/modules/dirA-xxx/config to reflect the correct directory
modify dirA-xxx/.git to reflect the correct directory
run git submodule status
if return error: No submodule mapping found in .gitmodules for path dirA-xxx. This is due to dirA-xxx is not existing, yet it is still tracked by git. Update the git index by: git rm --cached dirA-xxx
Try with git submodule foreach git pull.
I didn't go through the actual study of git submodule structure, so above steps may break something. Nonetheless going through above steps, things look good at the moment. If you have any insight or proper steps to get thing done, do share it here. :)
文件夹映射可以在.git/modules文件夹中找到(每个文件夹都有参考其工作树的配置文件),因此确保这些文件夹对应于.gitmodules和.git/config中的配置。
因此.gitmodules有正确的路径:
[submodule "<path>"]
path = <path>
url = git@github.com:foo/bar.git
在[core]部分的.git/modules/<path>/config中,你有你的<path>的正确路径,例如。
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
worktree = ../../../<path>
如果在.git/modules中没有正确的文件夹,那么你必须去你的子模块目录并尝试git reset HEAD——hard或git checkout master -f。如果这没有帮助,你可能想删除所有对损坏子模块的引用,然后重新添加它,然后参见:重命名git子模块。
