Git Bash: Could not open a connection to your authentication agent [duplicate]

Answer 1

I was struggling with the problem as well.

After I typed $ eval 'ssh-agent -s' followed by $ssh-add ~/.ssh/id_rsa

I got the same complain: "Could not open a connection to your authentication agent". Then I realize there are two different kind of quotation on my computer's keyboard. So I tried the one at the same position as "~": $ eval ssh-agent -s $ ssh-add ~/.ssh/id_rsa

And bang it worked.
