이벤트 : xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools)

% brew update
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Updated 3 taps (homebrew/core, homebrew/cask and homebrew/cask-fonts).
#...省略...

원인 : OS 업데이트에서 XCode의 CommandLineTools / usr 디렉토리의 bin 디렉토리가 분실되었기 때문에?

# おぉ、エラーメッセージにあるbinディレクトリがない！
% ls -la /Library/Developer/CommandLineTools/usr
