Git 本地连不上远程报错--WARNING: REMOTE H

使用git pull拉取远端代码时，发生如下报错

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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 ECDSA key sent by the remote host is
SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.
Please contact your system administrator.
Add correct host key in /c/Users/xxxx/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /c/Users/xxxx/.ssh/known_hosts:2
ECDSA host key for gitlab.xpaas.lenovo.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.

根据报错提示：Offending ECDSA key in /c/Users/xxxx/.ssh/known_hosts:2
去电脑这个路径找到known_hosts文件，因为我的这个提示是2，所以删掉第二行fingerprint就行。
再使用git pull重新获取fingerprint即可。
