原因

本地没有生成SSH key.

1. generate SSH key;

$ ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

按照提示进行；

2. add your SSH key to the ssh-agent.

$ eval "$(ssh-agent -s)"
$ ssh-add ~/.ssh/id_rsa

3. add the SSH key to your Github account.

Paste the above copied outpur into your Github profile -> Settings -> SSH and GPG Keys -> Add new SSH key

~/../code/shell_learning$ git push origin master
To git@github.com:**/shell_test.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'git@github.com:**/shell_test.git'
hint: Updates were rejected because the remote contains work that you do

解决方法：

利用强覆盖方式用你本地的代码替代git仓库内的内容

 git push -f

参考

1. github_issue;

2. Generating a new SSH key and adding it to the ssh-agent;

3. git_push_error;
