bash - Github 权限被拒绝 : ssh add agent has no identities

Question

这是我第一次访问 GitHub，我没有使用控制台的经验。我在使用 Bash 的 MacBook 上。当我尝试访问 GitHub 时，我得到了这个:

git clone git@github.com:dhulihan/league-of-legends-data-scraper.git
Cloning into 'league-of-legends-data-scraper'...
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

我已尝试按照 Github 页面上关于权限被拒绝的说明进行操作。

当我使用 ssh -vT git@github.com 时，我得到以下信息:

OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011

接下来，eval "$(ssh-agent -s)" 返回“Agent pid 2314”， 但是 ssh-add -l 返回“代理没有身份。”

这就是我被困的地方。

此 answer 中的完整详细信息.

综上所述，当 ssh-add -l 返回“The agent has no identities”时，这意味着 ssh 使用的 key (存储在 ~/.ssh/id_rsa、~/.ssh/id_dsa 等)要么丢失，要么不为 ssh-agent 所知，是身份验证代理，或者他们的权限设置不正确(例如，全局可写)。

如果您的 key 丢失或者您没有生成任何 key ，请使用 ssh-keygen -t rsa，然后使用 ssh-add 添加它们。

如果 key 存在但 ssh-agent 不知道(比如它们在非标准文件夹中)，请使用 ssh-add/path/to/my-non- standard-ssh-folder/id_rsa 添加它们。

参见 this answer如果您在使用 ssh-add 或 ssh-agent 时遇到问题。
