@ 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:/qMkcD5izb73F2m0RhJmRqxbQMvgLRSXvCDyICsuOR4.
Please contact your system administrator.
Add correct host key in /c/Users/\347\250\213\345\205\210\347\224\237/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /c/Users/\347\250\213\345\205\210\347\224\237/.ssh/known_hosts:1

在C盘我的用户目录文件夹下有个 .ssh 目录。里面有个 known_hosts 文件，就是这里面的信息导致的，删除就好了
