git在子模块中时找不到索引(“索引文件打开失败:不是目录") [英] git failing to find the index when in submodule ("index file open failed: not a directory")
问题描述
在新的git仓库中，添加子模块并将其更改为子模块目录后，大多数git命令在子模块中运行时失败，并显示以下错误:
On a fresh git repo, after adding a submodule and changing to the submodule directory most git commands fail when run within the submodule with the error:
fatal: index file open failed: Not a directory
用于重现此问题的全套命令:
The full set of commands to reproduce the issue:
> git init .
Initialized empty Git repository in /Users/drh/code/personal/Experiments/git-test/.git/
> git status
On branch master
Initial commit
nothing to commit (create/copy files and use "git add" to track)
> git submodule add git@github.com:mitsuhiko/flask.git thirdparty/flask

推荐答案
That is because there isn't a commit yet in the parent repo (meaning no HEAD, and no master branch).
As you have detected, the GIT_DIR for the parent repo might be set too late for the submodule to use.
That would be a good bug to report if none of the git submodule tests cover that scenario.

我认为其他一些应用程序(我怀疑是 I think that some other application (I suspecting 这篇关于git在子模块中时找不到索引(“索引文件打开失败:不是目录")的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！virtualenv，尽管无法复制)正在设置GIT_DIR.
virtualenv, though can't reproduce) was setting GIT_DIR.
