事象

HomebrewでGUIのWiresharkをインストールしようとしてbrew install --cask wiresharkって叩いたらError: It seems there is already a Binary at '/opt/homebrew/bin/idl2wrs'.って怒られた。

$ brew install --cask wireshark

一瞬Applicationsディレクトリ内にWireshark.appが現れるのに、その直後にRemoving App '/Applications/Wireshark.app'って言って消されちゃうのとっても悲しい。消さないで。

解決

すでにCLI版のWiresharkをインストールしてたので、brew remove wiresharkでそれを取り除いてやり直したらうまくいった。

$ brew remove wireshark
