- 前情
- install/reinstall均失敗，提示鏈接文件不存在
- 檢查鏈接文件是存在的
- debug查看詳情，關鍵的報錯信息還是這條文件或目錄不存在
- 確認鏈接的目標文件是否存在，結果確實不存在
- 刪除鏈接文件，重新brew install，OK
前情
在之前的MBP上是安裝過nmap的，也是正常使用的。最近換了新的MBP，系統升級到了macOS Monterey 12.1，之前的數據是用蘋果的時間機器遷移過來的；因為機器的CPU從x86架構變成了arm架構，有部分軟件不能正常工作，已經陸續做了修復。
今天發現nmap也不能正常使用了，一番小鼓搗修復了，問題的處理很簡單，但是在網絡上搜索相關錯誤關鍵字貌似沒有相關的Case，因此還是簡單記錄一下，方便后面的同學。
此類問題應該是會出現在「之前通過homebrew安裝過某些軟件」，但是「軟件的鏈接文件失效」的場景。解決方法也是具有一定的通用性的。
以上。
