FATAL Something's wrong. Maybe you can find the solution here: https://hexo.io/ocs/troubleshooting.html

报错的原因可能是网络封禁了 22 端口，可通过 GitHub 提供的备用地址 ssh.github.com:443 连接：

在 ~/.ssh/ 目录下创建或编辑 config 文件（Windows 路径为 C:\Users\你的用户名\.ssh\config），添加以下内容：

1
2

5
plaintext
Host github.com
  HostName ssh.github.com
  Port 443
  User git

保存后执行 ssh -T git@github.com，此时会自动通过 443 端口连接，若提示 Hi [你的用户名]! You’ve successfully authenticated… 则说明配置成功。

经过上面配置config 文件后，测试发现 hexo d 命令可以顺利发布博客了。
