【问题描述】：

我正在尝试使用 ssh 协议连接到远程 github 存储库。
之后
git remote add origin ssh://username@github.com/foo/project.git
git 远程显示来源
产量：

Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

到同一个项目的 https 连接工作得很好，但我每次访问远程存储库时都必须登录（顺便问一下，我能以某种方式包抄它吗？）。
SSH 密钥存在并且用户可以访问它们。谁能告诉我是什么问题？

【问题讨论】：

标签： git github ssh

【解决方案1】：

git remote add origin ssh://username@github.com/foo/project.git

这不应使用username，而应使用git，如：

git remote add origin ssh://git@github.com/foo/project.git

【解决方案2】：

您似乎没有将 SSH 密钥添加到您的 GitHub 帐户。看看这个Doc 怎么做。

【讨论】：

是的，我确实将我的公钥添加到了我的 git 帐户中，从日志来看没问题。

【解决方案3】：

假设您已将正确的公钥添加到您的 GitHub 帐户，并且您对远程存储库拥有适当的权限，我猜这个问题与您的私钥有关。

您应该确保您的私钥被命名为id_rsa，或者您有ssh-agent 正在运行并且已添加密钥。如果您想运行 ssh-agent 并添加密钥，请尝试以下操作：

$ eval `ssh-agent`
$ ssh-add /path/to/private_key
