试试这个，对我很管用。

git remote rm origin
git remote add origin https://github.com/your-username/{{project-name}}.git

有时ssh凭证是安装在你的电脑上与github回购通信。 当你设置新的repo:如果你添加了https格式的origin，你的git凭证管理器不能找出repo。

检查产地格式

git remote -v

https格式的来源

origin  https://github.com/username/repo_name.git

ssh格式的原点

origin git@github.com:username/repo_name.git

删除https格式的origin

git remote remove origin

添加ssh格式的origin

git remote add origin git@github.com:username/repo_name.git

如果您正在使用访问密钥，请在创建访问密钥时给予适当的权限(我尝试了所有权限，它可以工作)

我遇到了同样的问题，但是当我发现我已经从另一个帐户创建了存储库，并试图从另一个帐户推送代码时。这就是现在我只需要给访问另一个帐户和问题解决。你会发现从

操作系统

使用VS Code和一个没有密码的密钥:

removed eval "$(ssh-agent -s)" line from my ~/.zshrc file to stop running it in the background (first step on Github's Generating a new SSH key article) verified my .ssh/config entry for *.github.com did not have a UseKeychain line used simply ssh-add ~/.ssh/id_ed25519 with NO --apple-use-keychain on VS Code "Git: Add remote..." allowed/authorized my Github account connection (you don't really need to add a remote) applies a new "vscodevscode.github-authentication" entry in Mac's Keychain Access app closed all shells and VS Code, restarted and the repo is now always found

因为您可能没有首先将远程git存储库标识到您的终端。

git remote set-url origin https://github.com/MyRepo/project.git

然后,

git add .
git commit -m "initial commit"
git push origin master
