【問題1】：每天git push代碼都好好的，今天也不知道為啥，傲嬌起來了，報了這樣一個錯誤：No supported authentication methods available(server sent:pubickey)，然后就來問度娘了，一位網友提供了如下解決方法：
將Tortoise默認的SSH客戶端修改為Git服務的SSH客戶端，即D:\software\TortoiseGit\bin\TortoiseGitPlink.exe修改為D:\software\Git\usr\bin\ssh.exe。

恩，“沒有認證方法”的問題解決了，又來問題了：fatal: Could not read from remote repository.Please make sure you have the correct access rights and the repository exists，但是我明明在github里配置了ssh key啊，于是另一個網友又提供了解決方法：把.ssh目錄下的known_hosts文件刪除。
最終，可以push代碼了。

【問題2】：IDEA中使用git push代碼時遇到如下報錯：WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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:xnm0q+BqBcS4V4hbst3zE9U7AabUGi5RquzA5kP/bfk. Please contact your system administrator. Add correct host key in /c/Users/admin/.ssh/known_hosts to get rid of this message.

刪除C:\Users\admin\.ssh目錄下的known_hosts即可。
