在将本地Git库推送到Github时，会莫名其妙的报一些错误
如：
$ git push -u origin master
The authenticity of host 'github.com (52.74.223.119)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)?
Host key verification failed.
fatal: Could not read from remote repository.
解决方案：不能直接回车，要输入yes
