新问题不能提交到github了
➜ 51xpage.github.com git:(master) git push

意思就是2021以后不能用密码了呗，要用key了呗
赶紧去弄个key去，测试一下
ssh -T 51xpage@github.com
Warning: Permanently added the RSA host key for IP address '20.205.243.166' to the list of known hosts.
51xpage@github.com: Permission denied (publickey).
学个新技能，看看ssh是咋弄的，多个v
看起来是会在 knows_host 里面留下点啥
ssh -vT 51xpage@github.com

统一是 git@github.com
ssh -T git@github.com
改成这个就可以了，啥情况呀
还是不行
但是git push还是不行，继续，还是要输入用户名密码
修改一下 .git/config 里面的地址，https改成ssh， 好像还是不行，奇怪了
Github permission denied: ssh add agent has no identities
试试看
ssh-add ~/.ssh/id_rsa
总结一下失败状况
现在的情况是 ssh -T git@github.com 成功，但是git push失败 这里有点细节，ssh -t 会提示认证，git push也会提示 ssh的提示是
Warning: the ECDSA host key for 'github.com' differs from the key for the IP address
Are you sure you want to continue connecting (yes/no)? yes
git push的提示是
Warning: the ECDSA host key for 'github.com' differs from the key for the IP address
不说一毛一样的，也是一毛一样了。
最后居然是这样解决的
vim .git/config, 地址改成 git@github.com:51xpage/51xpage.github.com.git 也就是ssh的地址，好像可以了，这个地址是从网页上拷贝下来的
总算可以提交了，但是有很多内容看起来是不合适？

这个问题反正也是出现过几次，换了网络居然就好了，就是高调上网就好了，奇怪了
