Troubleshooting（macOS系统）

看了很多博客和官方文档，我的解决方法如下：

先查看一下配置信息

$ ssh-add -l

The agent has no identities.

如果是这样，就是没有添加成功私人密钥，虽然已经生成了并且上传到了GitHub的ssh

$ ssh-add ~/.ssh/id_rsa #这个id_rsa应是你命名的私人密钥默认名，这里显示为没有此文件。我在生成时命名为了Jack_key

/Users/eveline/.ssh/id_rsa: No such file or directory

搞清楚了，开始行动

找到你生成的密钥文件路径，执行下面命令：

$ ssh-add path/to/your/ssh-key

Identity added: /Users/eveline/.ssh/Jack_key (/Users/eveline/.ssh/Jack_key)

好了，查看一下

$ ssh-add -l

2048 SHA256:Dd02IHmxxxxx...xxxxxxxxxFPsHkGxiVh48m0qI /Users/eveline/.ssh/Jack_key (RSA)

如此，则配置成功！

永久性添加密钥方法（仅Mac用户）：

$ ssh-add -K path/to/your/ssh-key

大功告成

$ ssh -T -v git@github.com即可
