Raspberry Pi 上的 ssh-agent 问题

Question

Weird thing - on my raspberry pi running raspbian buster i can't seem to use the ssh agent. I know that in some systems you have to manually eval the ssh-agent output unlike on things like OSX where ssh-add works out of the box. But for some reason on my Pi this is not working so I am getting the correct output from ssh-agent but when i try to then run ssh-add i still receieve the connection error:

eval ssh-agent -s
SSH_AUTH_SOCK=/tmp/ssh-8Dc0i8qfejW0/agent.7476; export SSH_AUTH_SOCK;
SSH_AGENT_PID=7477; export SSH_AGENT_PID;
echo Agent pid 7477;
root@raspberrypi:~/git# ssh-add ~/.ssh/githubpersonal
Could not open a connection to your authentication agent.

Anybody have any ideas?

Cheers

When you do:

eval ssh-agent -s

You are not setting environment variables. You need to do

eval "$(ssh-agent -s)"
