Deleting the .gitfolder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:
删除.git文件夹可能会导致 git 存储库出现问题。如果您想删除所有提交历史记录但将代码保持在当前状态，那么这样做是非常安全的，如下所示：
Checkout
git checkout --orphan latest_branchAdd all the files
git add -ACommit the changes
git commit -am "commit message"Delete the branch
git branch -D masterRename the current branch to master
git branch -m masterFinally, force update your repository
git push -f origin master
查看
git checkout --orphan latest_branch添加所有文件
git add -A提交更改
git commit -am "commit message"删除分支
git branch -D master将当前分支重命名为 master
git branch -m master最后，强制更新您的存储库
git push -f origin master
PS: this will not keep your old commit history around
PS：这不会保留您旧的提交历史记录

If you are sure you want to remove all commit history, simply delete the .gitdirectory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:
如果您确定要删除所有提交历史记录，只需删除.git项目根目录中的目录（注意它是隐藏的）。然后在同一个文件夹中初始化一个新的仓库，并将其链接到 GitHub 仓库：
git init
git remote add origin [email protected]:user/repo
now commit your current version of code
现在提交您当前版本的代码
git add *
git commit -am 'message'
and finally force the update to GitHub:
最后强制更新到 GitHub：
git push -f origin master
However, I suggest backing up the history (the .gitfolder in the repository) before taking these steps!
但是，我建议.git在执行这些步骤之前备份历史记录（存储库中的文件夹）！
