为什么报@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 SHA256:xnm0q+BqBcS4V4hbst3zE9U7AabUGi5RquzA5kP/bfk. Please contact your system administrator. Add correct host key in /c/Users/August/.ssh/known_hosts to get rid of this message. Offending RSA key in /c/Users/August/.ssh/known_hosts:1 RSA host key for [git.imooc.com]:80 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.
后删除.ssh目录下的known_hosts文件就可以解决呢？这个多余的文件是怎么产生的呢？
