VSCode&；Git问题：Can'；因为头部没有'；不要指向任何提交

我对VSCode有一个问题，当我想要撤消上次提交时，弹出消息是“不能撤消，因为HEAD不指向任何提交”

但我已经在shell中手动提交了它的工作

最后一次登录“输出”窗口：

git状态：

[DEV - -@- -]$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#   (use "git push" to publish your local commits)
#
# 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:   ---
#       modified:   ---
#       modified:   ---
#       modified:   ---
#
no changes added to commit (use "git add" and/or "git commit -a")

[DEV-->]$git状态
#论分行行长
#您的分支比“原始/主分支”早1个提交。
#（使用“git push”发布本地提交）
#
#未为提交而暂存的更改：
#（使用“git add…”更新将提交的内容）
#（使用“git签出--…”放弃工作目录中的更改）
#
#修改：---
#修改：---
#修改：---

未向提交添加任何更改（使用“git add”和/或“git commit-a”）

你能帮我修好git吗？

我回答自己，我有git 1.x。我切换到Git2.x，所有的问题都消失了，奇怪的是VSCode没有警告Git1.x有潜在的bug
