無法重新安裝自制軟件

Question

我試圖刪除自制軟件，以便我可以將它安裝在另一個帳戶上。但是在某個地方，我一定會搞砸的。我遵循常見問題解答中的卸載技巧，我想我設法部分刪除它。現在，當我嘗試釀造醫生時，我得到：

-bash: brew: command not found 

所以我asume它部分卸載。但是，當我運行自制軟件的安裝腳本，我得到以下信息：

It appears Homebrew is already installed. If your intent is to reinstall you 
should do the following before running this installer again: 
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup 

所以我嘗試室射頻的/ usr /本地/酒窖/usr/local/.git & &釀造清理，並得到：

現在我不知道該怎麼做，所以我可以重新安裝它。我不熟悉終端命令，所以可能是我錯過了一些簡單的東西，但請帶上建議。

嘗試

sudo rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

的，那麼你應該有權限。但是，當brew命令不存在時，brew cleanup將無法​​正常工作。但也許它會讓你在那之後重新安裝Homebrew。
