【git】No supported authentication methods available(server sent:pubickey)

【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)，然後就來問度娘了，一位網友提供了如下解決方法：

将Tortoise預設的SSH用戶端修改為Git服務的SSH用戶端，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裡配置了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

檔案删除。

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!
