Changes not staged for commit

问题复现

git commit -m "test"

提示信息为

On branch main
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
  (commit or discard the untracked or modified content in submodules)
        modified:   bdapp-qa/iOS-auto-tools (modified content)
        modified:   qa/auto-tools (modified content, untracked content)

Untracked files:
  (use "git add <file>..." to include in what will be committed)
         debt/
        .vscode/
        hackers/
        output.txt
        test/

原理

commit是将stage中的文件提交到本地仓库中（History或Repository）中。我们修改了代码，但只是在工作区修改的（Working Directory），stage中并没有修改，所以commit时检测不到提交到本地仓库的修改，于是提示“no changes added to commit”

解决

在这里插入图片描述
将这几个文件选择至少一个git add到暂存区，然后再commit即可

git add output.txt

git commit -m "1127"

在这里插入图片描述

warning: adding embedded git repository

问题复现

git add .

提示信息为：

warning: adding embedded git repository: hackers
error: 'test/' does not have a commit checked out
fatal: adding files failed

原理

添加了被嵌入的git仓库，根据提示，是由于test/文件夹里面的.git文件连接了另一个仓库，导致子文件夹的仓库信息和主文件夹的不一致，就是有个内嵌的子git仓库。

解决

cd test
rm -rf .git

error: src refspec master does not match any

问题复现

git push origin master:master

提示：

error: src refspec master does not match any
error: failed to push some refs to 'ssh://

原理：
本地没有master分支，或没有链接远程仓库或远程仓库没有master分支

解决方法：
修改当前本地分支名字为master

git branch -m master

Changes not staged for commit

问题复现：

git status

总是出现一些modified，并且无法通过git add或者git restore来修改
提示：

 (use "git add <file>..." to update what will be committed)
