这可能发生在您执行包含文件的签出时，这些文件本应由LFS跟踪(如.gitattributes中指定的那样)，但它们却被直接提交了。大多数情况下，您有另一个程序管理您的存储库，如git GUI或IDE。

这可能会令人沮丧，因为这些文件不知从哪里冒出来，阻止您进行签出。只要您将更改隐藏起来，它们就会返回!如果您陷入这种情况，一个快速的解决方法是在一个临时分支上提交这些更改，这样您就可以再次签出。

要真正解决这个问题，请确保将文件提交为LFS指针。这应该和使用git add一样简单。在提交之前使用git lfs状态检查你的工作。git lfs ls-files将显示lfs正在管理的文件。

git lfs状态是误导性的，因为当它真正列出所有更改时，它会读取git lfs对象以提交。您希望由LFS跟踪的文件应该读取类似于(LFS: c9e4f4a)或(Git: c9e4f4a -> LFS: c9e4f4a)的文件，而不是(Git: c9e4f4a)。

举例来说，我发现这是一个问题，当通过Xcode 9.2添加图像资产时，我添加了“CalendarChecked.png”，它会自动添加:

$ git status
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    new file:   Example/Assets.xcassets/CalendarChecked.imageset/CalendarChecked.png

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    modified:   Example/Assets.xcassets/CalendarChecked.imageset/CalendarChecked.png

$ git lfs status

Git LFS objects to be committed:

    Example/Assets.xcassets/CalendarChecked.imageset/CalendarChecked.png (Git: c9e4f4a)

Git LFS objects not staged for commit:

    Example/Assets.xcassets/CalendarChecked.imageset/CalendarChecked.png (File: c9e4f4a)

$ git add Example/Assets.xcassets/CalendarChecked.imageset/CalendarChecked.png`
$ git lfs status

Git LFS objects to be committed:

    Empty/Empty/Assets.xcassets/CalendarChecked.imageset/CalendarChecked.png (LFS: c9e4f4a)

Git LFS objects not staged for commit:

$

当一个明显的错误突然出现时，我们的团队是这样做的:

Disable lfs for that specific type file (modifying .gitattributes or via SourceTree menus) The change will dissapear and you will see a change on .gitattributes instead Remove the problem: 3.1 One solution is to execute git reset --hard. Another way, discard changes. Sometimes the file will not come up again. 3.2.1 If the previous solution doesn't work, repeat 1 and 2. Then make sure that this branch you are in (A) has already commited and pushed everything except those annoying files. Then commit your change, but not push. 3.2.2: Go to another branch (B) 3.2.3: Remove that local branch (A) where you performed the commit to .gitattributes, forcing the removal even when it says there's a commit that hasn't been pushed. It will forget that commit (it can afterwards be removed via GC or whatever but it's not a big deal if the file that has the error is not huge) 3.2.4: Checkout the branch A again. It will download the previous status of the repository without the annoying files and LFS settings set up the correct way.

这招总是管用的!

这些解决方案都不适合我，但我拼凑了一些资源，最终解决了所有这些问题。

Push any changes you don't want to lose If you can... If not, or if you don't care about your changes, press on. Stop Everything SourceTree, any servers, file explorers and browsers. Sometimes this stuff won't work if it's being used somewhere else. When in doubt, stop it - with this it's better to overkill. Also, go into Task Manager, force quit any bash.exe processes. Git Bash tends to hold files open after you close the window. Open a Command Window (or Terminal) cd to your local repo. Uninstall lfs > git lfs uninstall Then it'll say something like: Hooks for this repository have been removed. Global Git LFS configuration has been removed. Reset > git reset --hard It'll go through a lot of output probably... Reinstall lfs > git lfs install This may again say it found files that should have been pointers but weren't. That's OK, keep going! Pull with lfs > git lfs pull Hopefully pulling with lfs will overwrite the files that got borked. A few of my sources said at this point their repo was working again, but not me personally. You can open SourceTree or whatever to check if you want, but you may have to start from the top if it didn't work. Migrate The core issue here is that lfs, instead of downloading large files like audio, video, images - anything larger than 1Mb - it just points to them on a server. This is useful if you have a bunch of large files, you're not pulling down all that stuff. So your local repo is smaller and nimbler. However, through circumstances I'm not sure about, it seems possible to corrupt the pointers. I'm sure this is an issue that the lfs people are aware of and are working on, but for now we have to work it out ourselves. What we've done so far is uninstall lfs delete everything reinstall lfs pull everything So now we have all these things in our folder that are either files or pointers to files, and lfs needs to figure out if any files should be pointers and vise versa. And hopefully by performing the steps above we deleted the corrupted pointers. So we're going to perform migrate to kick off the procedure that goes through the files on the repo, and if they're greater than 1Mb, lfs is going to replace them with a pointer. > git lfs migrate More Errors Here's a point at which others have stopped and said they were working again, but not me. I got an error: Error in git rev-list... exit status 128 fatal: bad revision '...v1.0.0' @guneyozsan over at a github help page, posted this final piece to the puzzle, even though it didn't fix his issue. > git lfs migrate info --include-ref=v1.0.0 Notice the version matches the version that errored - v1.0.0. You will need to replace v1.0.0 with whatever version you got in your error. I haven't found a source on why this error occurs but my guess is that the lfs version number generated by migrate on your local repo doesn't match the source version. For me, all this started when SourceTree crashed during a push and I forced a machine reboot, and when that happens, lfs doesn't know how to deal with it, so it just gets stuck in this loop where it's trying to update, but it can't read the corrupted data. Hence the lengthy troubleshooting. Stash and Pull

当您打开SourceTree时，您可能会看到它想要将您的所有文件添加回来。不要那样做。藏起来，然后拉出来。

然后，恐怖事件有望结束。如果没有，这个git集线器页面或这个可能会帮助你更多，但这对我来说是有效的。

上面的命令对我都没用，我在这里找到了答案

git status -s | cut -c 4- | xargs git update-index --assume-unchanged
rm .git/index && git reset

下面的进程将添加一个提交，将所有应该是lfs指针的二进制文件替换为lfs指针。

Clean working copy completely. Together with the force add below this prevents any files getting added or removed due to .gitignore patterns. git clean -dfx git reset --hard git checkout -- . Add remove for everything to staging area. Working copy will not be touched. git rm --cached -r . Readd all files from working copy again. This will basically undo the previous command but will reevaluate lfs filters. Use -f to ignore .gitignore. All files present were previously checked in and should get added again. git add -f . You staging area now should only contain the binary files that previously raised the 'should have been pointers' error. git commit -m "moved files to lfs"

问题来自于git LFS在.git属性中标记为要跟踪的文件类型与一些已经在传统的非LFS版本控制下的匹配文件之间的不匹配。

所以这里最简单的解决方法是暂时删除.gitattributes文件:

git rm .gitattributes
git reset .
git checkout .

之后，您可以结帐任何其他分支。

另外一个建议:当添加一个新的文件类型到git LFS时，最好不要手动修改.gitattributes，而是通过运行:

git lfs track PATTERN

其中PATTERN是匹配文件的模式，例如*.so

通过这种方式，所有匹配新的跟踪模式的非LFS版本文件将被标记为dirty，并可以简单地添加，即转换为git LFS(文件指针)。
