一旦你启动了SSH代理，使用:

eval $(ssh-agent)

做:

To add your private key to it: ssh-add This will ask you your passphrase just once, and then you should be allowed to push, provided that you uploaded the public key to Github. To add and save your key permanently on macOS: ssh-add -K This will persist it after you close and re-open it by storing it in user's keychain. If you see a warning about deprecated flags, try the new variant: ssh-add --apple-use-keychain To add and save your key permanently on Ubuntu (or equivalent): ssh-add ~/.ssh/id_rsa

似乎您的本地repo没有更新ssh密钥…至少这是我从HTTPS到ssh时遇到的情况。

你远程重置了吗?

git remote set-url origin <ssh url>

如果你没有使用GitBash并且在Windows上-你需要使用这个命令启动你的ssh-agent

start-ssh-agent.cmd

如果您的ssh代理没有设置，您可以以管理员身份打开PowerShell并将其设置为手动模式

Get-Service -Name ssh-agent | Set-Service -StartupType Manual

如果上面的解决方案不适合我，需要检查的一件事是您实际上也有公钥(通常是id_rsa.pub)。不这样做很不寻常，但这就是我的原因。

从私钥创建公钥:

ssh-keygen -y -f ~/.ssh/id_rsa > ~/.ssh/id_rsa.pub

如果你碰巧用的是鱼，这里有一个要点:

# config.fish
if not pgrep -f ssh-agent > /dev/null
  eval (ssh-agent -c)
  set -Ux SSH_AUTH_SOCK $SSH_AUTH_SOCK
  set -Ux SSH_AGENT_PID $SSH_AGENT_PID
  set -Ux SSH_AUTH_SOCK $SSH_AUTH_SOCK
end

也许不是最安全的方法来解决这个问题，但不要设置密码短语，这是可选的。如果您不设置密码短语，它将不会请求它。你可以用更改密码

$ ssh-keygen -p -f ~/.ssh/id_ed25519
> Enter old passphrase: [Type old passphrase]
> Key has comment 'your_email@example.com'
> Enter new passphrase (empty for no passphrase): [Type new passphrase]
> Enter same passphrase again: [Repeat the new passphrase]
> Your identification has been saved with the new passphrase.
