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!

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"

在我的例子中，它是一个lfs规则下的文件(我假设它是在没有安装lfs或其他东西的情况下检入的)。

所以我在.gitattributes文件中找到了它的扩展名，并将这一行注释为

#*.7z filter=lfs diff=lfs merge=lfs -text

保存这个.git属性，然后git状态显示没有问题。

之后，我取消了这一行的注释(删除了#)，保存了.gitattributes和git状态仍然显示没有问题。

确保您已经安装了git lfs 2.5或更高版本(此处下载)。

检查你正在使用你下载的git lfs版本(我是2.7.2):

>git lfs version
git-lfs/2.7.2

Run:

Git LFS迁移导入-修复-一切

拉出分支并修复任何合并冲突。

在这个github评论中找到。

自从git lfs 2.5.0以来，有一个新的命令可以让这变得更容易(docs):

git lfs migrate import --no-rewrite "broken file.jpg" "another broken file.png" ...

这将文件“迁移”到git lfs中，根据.gitattributes应该在lfs中，但目前没有(这就是出现错误消息的原因)。

——no-rewrite阻止git将此应用于旧的提交，而是创建一个新的提交。

使用-m "commitmessage"为该提交设置一个提交消息。
