problem 1:
The authenticity of host ‘ (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 ‘’ (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.

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
