解决报错：@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @

执行git push推送代码的时候，报错：

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
SHAXXX:uNiVztksCsDhcc0u9e8BujQXVUpKZIDTMczCvj3tXXX.
Please contact your system administrator.
Add correct host key in /c/Users/XXX/.ssh/known_hosts to get rid of this message.
Offending RSA key in /c/Users/XXX/.ssh/known_hosts:1
RSA host key for github.com has changed and you have requested strict checking.
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

原因：一般发生在重装系统上，本地最早已经远程连接过服务器，生成了本地远程连接信息，当重装系统后，本地密钥信息还在，但远程已经重装了系统。应该是重新生成本地远程连接信息就好了。
解决方案：
1、打开电脑存放ssh公私钥的目录：C:\Users\XXX.ssh，删掉known_hosts文件

2、重新运行git push，会出现选择提示，输入yes然后回车：

3、重新运行git push即可成功推送
