Homebrew 如何从brew中删除virtualbox，以获取；没有这样的文件或目录；错误消息

以下是我尝试过的：

➜  ~ brew rm virtualbox
==> Uninstalling Cask virtualbox
Error: Failure while executing; `brew cask uninstall virtualbox-extension-pack` exited with 127. Here's the output:
No such file or directory - brew

➜  ~ brew cask rm virtualbox
==> Uninstalling Cask virtualbox
Error: Failure while executing; `brew cask uninstall virtualbox-extension-pack` exited with 127. Here's the output:
No such file or directory - brew
➜  ~ 

---

我终于用以下方法解决了这个问题：

brew cask install --force virtualbox virtualbox-extension-pack
brew cask rm virtualbox-extension-pack virtualbox
