1. 起因
给自己的 github 改个名，顺便就给原来 Hexo 对应的仓库也改了个名。然后发现 ub='hexo clean && hexo generate && hexo deploy' 失败了，报错如下：
INFO Deploying: git
INFO Clearing .deploy_git folder...
INFO Copying files from public folder...
INFO Copying files from extend dirs...

} Something's wrong. Maybe you can find the solution here: %s https://hexo.io/docs/troubleshooting.html
划重点：Please make sure you have the correct access rights and the repository exists.
好像我的 ssh 配置出问题了，想来那就重新配一遍吧，顺便记录下。
2. 配置过程
2.1 生成 SSH 密钥
ssh-keygen -t ed25519 -C "your_email@example.com"
**注意：**如果您使用的是不支持Ed25519算法的遗留系统，请使用：
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
> Enter a file in which to save the key (/Users/YOU/.ssh/id_ALGORITHM): [Press enter]
> Enter passphrase (empty for no passphrase): [Type a passphrase]
> Enter same passphrase again: [Type passphrase again]å
这时候在 ~/.ssh/ 下应该看到如下文件：
2.2 将 SSH 密钥添加到 ssh-agent
-
在后台启动 ssh-agent
$ eval "$(ssh-agent -s)" > Agent pid 51024 -
打开文件
~/.ssh/config，然后修改文件以包含以下行Host github.com AddKeysToAgent yes IdentityFile ~/.ssh/id_ed25519 -
将 SSH 密钥添加到 ssh-agent
ssh-add ~/.ssh/id_ed25519
2.3 将 SSH 公钥添加到 GitHub 上的帐户
-
将 SSH 公钥复制到剪贴板
$ pbcopy < ~/.ssh/id_ed25519.pub -
在 GitHub 任何页面的右上角，点击头像，然后点击设置
-
打开左侧的 SSH and GPG keys
-
New SSH key
起个好听的名字，然后把第一步中复制的公钥粘贴进去
2.4 恭喜🎉，快来测试下吧
$ ssh -T git@github.com
> Hi Kudoryafuka3! You've successfully authenticated, but GitHub does not provide shell access.
