REMOTE HOST IDENTIFICATION HAS CHANGED!

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
SHA256:uNiVztksCsDhcc0u9e8BujQXVUpKZIDTMczCvj3tD2s.
Please contact your system administrator.
Add correct host key in /Users/caijialinxx/.ssh/known_hosts to get rid of this message.
Offending RSA key in /Users/caijialinxx/.ssh/known_hosts:1
Host key for github.com has changed and you have requested strict checking.
Host key verification failed.

Please make sure you have the correct access rights
and the repository exists.

Github 远程主机地址变更，导致 SSH 链接失败。解决方法：

  • 在 ~/.ssh/known_hosts 删除对应IP的host记录
  • 或者删除整个 ~/.ssh/known_hosts 文件

xcrun: error: invalid active developer path

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

更新完 macOS 版本之后，使用终端出现这个报错，是因为 xcode 在更新后可能会需要重新安装。执行下行命令重装 xcode 即可：

$ xcode-select --install
