最近提交代码出现了好多次提交不上的情况

Your branch is up to date with 'origin/master'.
error: cannot pull with rebase: You have unstaged changes.
error: please commit or stash them.

根据提示进行

git stash

但还是有问题，最后折腾了半天发现是以前的一次错误提交引起的，总算是解决了。

• 方法

1. 切换到项目的顶层目录

git chekcout .

把所有的改动全部删除

2.删除贬低代码时的附加改动（生成的文件等）

git clean -fd

3. 拉取代码

git pull

但此时有报错

Already up to date.

It seems that there is already a rebase-apply directory, and
I wonder if you are in the middle of another rebase.  If that is the
case, please try
        git rebase (--continue | --abort | --skip)
If that is not the case, please
        rm -fr "xxxxxxxxxxxxxxxxx/.git/rebase-apply"
and run me again.  I am stopping in case you still have something
valuable there.

找到了问题的根源

rm -fr "xxxxxxxxxxxxxxxxx/.git/rebase-apply"

4. 切换到 .git 目录

cd .git

5. 执行

rm -fr rebase-apply/

6.返回刚才的目录（顶层目录）

 cd ../

7.重新拉取代码

git pull
