为什么` `git rebase --continue`失败并出现gitmodules错误？

Question

我基于master创建了一个名为lab的分支。几个月后，我尝试根据master重新设置实验室分支的基础。首先有一个.gitignore冲突；在解决它之后，我运行了git rebase --continue，但它再次失败，这一次没有帮助信息告诉我如何继续这个rebase。如何根据master来调整实验室分支的基础？

git rebase --continue

The copy of the patch that failed is found in:

When you have resolved this problem, run "git rebase --continue".
If you prefer to skip this patch, run "git rebase --skip" instead.
To check out the original branch and stop rebasing, run "git rebase --abort".

Answer 1

.gitmodules存在于一个分支上，而不存在于另一个分支上。查看补丁文件，看看是哪一个，然后使用git add或git rm来决定是否需要.gitmodules文件作为rebase的结果。

Answer 2

尝试使用--merge修饰符运行rebase

git rebase --merge branchname
