一、 error: ‘my_project/’ does not have a commit checked out fatal: adding files failed
1、情景再现：
git add 提交文件到暂存区时报错
error: 'my_project/' does not have a commit checked out fatal:
adding files failed
2、原因：
提交项目子目录中有.git文件（可能是隐藏状态），显示隐藏文件即可
3、解决办法：
找到 .git 文件夹，删除！
二、 src refspec main does not match any
1、情景再现：
git push -u origin main 提交项目到远程仓库时报错
$ ahua win64 ~/Desktop/vue (master)
$ git push -u origin main
error: src refspec main does not match any
2、原因：
提交到远程仓库中的分支和本地的仓库的分支不一样，可以看到上面代码块中的分支是master（现在github主分支是main）
3、解决办法：
修改本地分支名为main即可
git branch -m oldBranchName newBranchName
三、warning: LF will be replaced by CRLF in node/node_project.The file will have its original line endings in your working directory
1、情景再现：
git add添加文件到暂存区时警告
warning: LF will be replaced by CRLF in node/node-project.
The file will have its original line endings in your working directory
2、原因：
这是因为在windows和unix下的换行符不一样，git bush是unix风格设计的，虽然git默认会自动转换，但是有时会出问题
3、解决办法：
禁止自动转换
git config --global core.autocrlf false
四、 ! [rejected] main -> main (fetch first) error: failed to push some refs to ‘https://github.com/xxxxxx’
1、情景再现：
git push origin main 提交代码到远程仓库时报错
! [rejected] main -> main (fetch first)
error: failed to push some refs to 'https://github.com/xxxxxx'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
2、原因：
远程仓库中的代码比本地仓库中的新（存在本地仓库没有的文件）
3、解决办法：
将远程仓库中的代码合并到本地即可
git pull --rebase origin main
