我有同样的问题，并发现我在~/中有另一个密钥文件。ssh到不同的GitHub存储库。不知怎么的，它代替了新的。

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

如果你正在使用Git桌面应用程序，那么你应该尝试从Git桌面应用程序中推和拉，而不是终端。它会帮助你的。

在Mac

如果您正在尝试克隆repo....然后这个问题可能会发生，因为你没有回购目前在github帐户目前在钥匙串访问。为了解决这个问题，请尝试使用帐户名进行克隆

Git 克隆 https://username@github.com/org/repo.git

取代

用户名与你的GitHub用户名 与您的组织名称 使用存储库名称进行回购

I was trying to clone a repo and was facing this issue, I tried removing all git related credentials from windows credentials manager after that while trying to clone git was asking me for my credentials and failing with error invalid username or password. This was happening because the repo I was trying to clone was under an organization on github and that organization had two factor auth enabled and git bash probably do not know how to handle 2fa. So I generated a token from https://github.com/settings/tokens and used the github token instead of password while trying to clone the repo and that worked.

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
