I try to use bitbucket for my android application. I have my repo on my account. I want to clone my project to local computer. For this I need to generate ssh key. I use this tutotial https://help.github.com/articles/generating-ssh-keys/ . And I have error "Could not open a connection to your authentication agent." when I make command "ssh-add ~/.ssh/id_rsa". Before it I "eval "$(ssh-agent -s)" and it show "Agent pid 32426". What is the problem?
