    problem 1:

    The authenticity of host ‘github.com (140.82.121.4)’ can’t be established.

    ED25519 key fingerprint is SHA256:+EiY3wvvVd58shbpZisF/zLDA0zPMSvHdkr4UvCOqU.

    This key is not known by any other names.

    Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

    Warning: Permanently added ‘github.com’ (ED25519) to the list of known hosts.

    Enter passphrase for key ‘/c/Users/user/.ssh/id_rsa’:

    solve:

    直接输入yes回车就好了，原因是新生成SSH Key（密钥）时，进行git clone或git push时，经常会出现该错误。

    解决方法：首先查看自己用户目录下的.ssh目录下是否有三个密钥文件。

    若只有两个的话，输入yes回车之后，会生成一个known_hosts文件。若是三个的话，请看下面的原因。

    原因2：github上的项目没有与本地仓库相关联。

    解决方法：重新进行git remote即可，若问题未解决，请看原因3。

    原因3：SSH Key不对。

    解决方法：①cat ~/.ssh/id_rsa.pub：查看ssh是否是自己的（若不是，SSH Key的问题，进行②③操作）。

    ②在git仓库同目录删除.ssh文件夹(隐藏文件夹)。

    ③重新生成ssh key : ssh-keygen -t rsa -b 4096 -C “邮箱”

    ④在生成的SSH Key复制到github上，新建一个SSH连接即可解决问题。

    注： 直接输入ssh-keygen -t rsa 生成密钥时可能会出现错误，这是只需找到git安装路径下对应的bin目录，将其路径加入path环境变量即可。

    problem 2：

    fatal: destination path ‘.’ already exists and is not an empty directory.

    意思就是：目标路径已经存在并且不是一个空目录。

    solve：

    打开工具->文件夹选项->查看->显示隐藏文件，终于发现了隐藏文件夹“.git”。

    删掉该文件夹后，再次执行git clone，成功拉下代码。

    problem 3:

    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:uNiVztksCsDhc5gat58BujQXVUpKZICAMczCvj3tD2s.

    Please contact your system administrator.

    Add correct host key in /c/Users/user/.ssh/known_hosts to get rid of this message.

    Offending RSA key in /c/Users/user/.ssh/known_hosts:2

    Host key for github.com has changed and you have requested strict checking.

    Host key verification failed.

    fatal: Could not read from remote repository.

    Cloning into ‘11’…

    The authenticity of host ‘github.com (140.82.121.4)’ can’t be established.

    ED25519 key fingerprint is SHA256:+DiY3wvvV6sfjixSpZisF/zLDA0zPMSvHdkr4UvCOqU.

    This key is not known by any other names

    solve：

    只需将.ssh下的密钥文件夹删除，重新生成密钥配置即可。

    注 .ssh所在目录：C:\Users\用户名.ssh
