为GitHub添加SSH key时出现“Could not open a connection to your authentication agent”错误的应对方案

$ ssh-agent -s
# Agent pid 59566
$ ssh-add ~/.ssh/id_rsa
Could not open a connection to your authentication agent.

那么执行

eval `ssh-agent -s`

后重新执行

$ ssh-add ~/.ssh/id_rsa

最后将public key添加在github

测试是否生效

$ ssh -T [email protected] 或者 ssh -vvv [email protected]
# Attempts to ssh to GitHub

没错误就是成功了
