无法重新安装自制软件

Question

我试图删除自制软件，以便我可以将它安装在另一个帐户上。但是在某个地方，我一定会搞砸的。我遵循常见问题解答中的卸载技巧，我想我设法部分删除它。现在，当我尝试酿造医生时，我得到：

-bash: brew: command not found 

所以我asume它部分卸载。但是，当我运行自制软件的安装脚本，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 

所以我尝试室射频的/ usr /本地/酒窖/usr/local/.git & &酿造清理，并得到：

现在我不知道该怎么做，所以我可以重新安装它。我不熟悉终端命令，所以可能是我错过了一些简单的东西，但请带上建议。

尝试

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

的，那么你应该有权限。但是，当brew命令不存在时，brew cleanup将无法​​正常工作。但也许它会让你在那之后重新安装Homebrew。
