Why do I get “fatal: git status --porcelain failed”?

问题:

This is a huge pain in the bum. I've got this a few times before and I don't understand why. 5 mins ago the repo was fine and working, I move some files around (which is all cool and all) and git poops its pants. Any idea why this happens? How can I fix it apart from cloning the repo, moving the files, etc...

回答1:

Oh dear I'm such a fail. It looks like the problem stems from Flash Builder copying over other .git repos into sub folders. The answer is to remove all .git folders that aren't the repo's one.

回答2:

In case it helps anyone else, I just encountered the same issue and found that running git init in the project root fixed it.

回答3:

I ran into this error because of a corrupted/not properly initialized submodule (with its own .git subfolder). I temporarily deleted the submodules folder and used git init in the main project's root. Fixed the problem for me.

回答4:

I know this is an old thread, but I just had the same problem and ended up solving in a different way. The git init didin't work for me. Posting here, in case it's useful to anyone else.

My repository has two submodules. After rebasing I started getting the error fatal: git status --porcelain failed.

The solution was to verify the property worktree in every submodule config file - e.g. /.git/modules//config.

I had one invalid path for the worktree property. It was linking to an unexisting folder that was changed and merged to master - probably due an error resolving conflicts.

回答5:

I had the same issue. Running git status in my root project's directory produced the following error:

fatal: This operation must be run in a work tree fatal: 'git status --porcelain' failed in submodule js/object-subscribe 

Running git status in the affected submodule (js/object-subscribe) would produce this error:

fatal: This operation must be run in a work tree 

Running git init in that submodule's folder did it for me.

回答6:

I don't have any .git folders in my repo, but anytime I copy my new files into my folder to update my app, I am still getting index corrupt porcelain failed errors. I don't understand how updating files would corrupt this or how to fix it. Anyone have further insight on this?

回答7:

Usually, git creates a hidden directory in project's root directory (.git/)

When you're working on a CMS, its possible you install modules/plugins carrying .git/ directory with git's metadata for the specific module/plugin

If you do not want to use git's submodules feature, quickest solution delete all .git directories except root git metadata directory. If you do so, git will not consider those modules as project submodules.

cd /path/to/your/project/code find ./ | grep ".git/index" 

Once located delete ".git" all directories except the root one, but if you deleted it initialize your repo again

回答8:

.git is a file in submodules and points to a directory located in your root .git directory.

In my case, I was mounting a git directory in docker and checking status there. The .git file of this submodule contained an absolute path which was invalid in docker. I edited this .git file to change the gitdir path to a relative path.

Git version: 2.7.4

回答9:

In my case after moving moduleA/mySubmodule to moduleB/mySubmodule using git mv moduleA moduleB with git 2.12.2, I ran into the follwoing error:

$ git status fatal: Could not chdir to '[../]moduleA/mySubmodule': No such file or directory fatal: 'git status --porcelain' failed in submodule mySubmodule fatal: 'git status --porcelain' failed in submodule moduleB 

Then I did the follwing (Maybe in not this order)

1. Manually update .gitmodules entry to moduleB
2. Enter .git/modules and rename old module folder
3. Enter moduleB and delete submodules folder
4. Run git submodule sync and git submodule update

After that, I could run git status again without problems.
