git rebase 多次， 发现反而出了问题。
git rebase
发现下面的错误（一开始没有注意）。

后面发现 某些东西被 rollback了！ 我做的修改呢？？？ 我的天啊， 竟然存在 External Change！！！ 而我并没有在外部对当前项目，做任何修改（难道误操作） 。
后面发现也不是误操作， 而是 git reabse 的特性， 从日志来看， 因为出现了Rebase Error， 导致了 Local changes were not restored， 进而“ changes were saved to shelf. Update is not complete, you have unresolved merges in your working tree Resolve conflicts, complete update and restore changes manually.” ，

我的 文件恢复到了 clean 状态， 所以我的未提交的修改也丢失了， 但是实际上也没有丢失， 而是到了 shelf：
git rebase 不行 ，那就git merge 吧， 大不了出现冲突解决一下：
git merge 呢， 至少是可以把远程的提交拉取下来。 git rebase 不会。
