1、改邮箱
git config --global user.name "git名称"
git config --global user.email“邮箱@email.com"
2、删除.ssh文件夹（直接搜索该文件夹）下的known_hosts
3、git输入命令
$ ssh-keygen -t rsa -C "邮箱@email.com"
接着出现：
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/your_user_directory/.ssh/id_rsa):
一路按下回车
会生成id_rsa和id_rsa.pub，复制pub的到git上去
GIT，lease make sure you have the correct access rights
