1、问题

        使用git pull代码的时候，报了如下错误：

$ git pull
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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

Please contact your system administrator.

2、解决办法

        其实bash面板中已经给出了提示，在C盘的users目录下找到known_hosts文件，在里面的第一行有一个ip为172.16.xxx.xxx的一行类似秘钥的内容，将这一行整段删掉，再重新拉取，就可以了！！！

        我删除的内容如下：

172.16.xx.xxx ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBPTkozctTDmlOIu7b8RgRBr2u9GRksPCcoggBotigx/8qGobyllGbn9oKDxweTar......

        另外提示一下，有的人这个known_hosts文件里，可能不止一行关于bash里提示的ip相关的内容，可能有3行，或更多，如：

172.16.xx.xxx ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBPTkozctTDmlOIu7b8RgRBr2u9GRksPCcoggBotigx/8qGobyllGbn9oKDxweTar......

172.16.xx.xxx ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBPTkozctTDmlOIu7b8RgRBr2u9GRksPCcoggBotigx/8qGobyllGbn9oKDxweTar......

172.16.xx.xxx ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBPTkozctTDmlOIu7b8RgRBr2u9GRksPCcoggBotigx/8qGobyllGbn9oKDxweTar......

.....

则需要将bash中提示到的ip相关的行内容，全部删除掉，才可以正常使用git功能啦！！！！
