1.现象

fatal: unable to access 'https://github.com/livingbody/star_world/': OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 10054
(base) PS H:\livingbody\star_world>

2.原因
 

为了验证我的猜想，我需要查看这个项目的remote到底是什么，使用以下命令

(base) PS H:\livingbody\star_world\star_world> git config --get remote.origin.url
https://github.com/livingbody/star_world.git

3.解决办法

(base) PS H:\livingbody\star_world\star_world> git remote set-url origin git@github.com:livingbody/star_world.git
(base) PS H:\livingbody\star_world\star_world> git config --get remote.origin.url
git@github.com:livingbody/star_world.git
(base) PS H:\livingbody\star_world\star_world> git push

4.总结分析
 

这次问题的解决涉及到两个核心知识。

ssh keys的正确设置
只有git协议才可以使用ssh-keys文件，从而实现一键git push。https协议只支持账户密码输入。雪上加霜的是，在今年8月13日以后，git不再支持https协议。
