MacOS brew cask安装VirtualBox遇到的问题
问题一：Cask ‘virtualbox’ is already installed.
如果不是通过Homebrew安装的virtualbox，在使用brew cask install virtualbox安装virtualbox的的时候，会提示：
Warning: Cask 'virtualbox' is already installed.
那么就需要重新安装virtualbox，命令：
brew cask reinstall virtualbox
如果还不巧，你的virtualbox刚好在运行中，又会提示：
Failed to unload org.virtualbox.kext.VBoxDrv - (libkern/kext) kext is in use or retained (cannot unload).
那么，就需要网上拉日志，找到：
Warning! Found the following active VirtualBox processes:
这些是运行中的虚拟主机列表，其中第一列是它们的 ID，用kill命令关闭服务，如：
kill 234
然后再重新安装：
brew cask reinstall virtualbox
问题二：Error: Failure while executing;
安装virtualbox的最后一步会要求输入电脑的登陆密码，不过在你输入密码后，可能还是会提示错误，这是因为权限的问题，主要信息如下：
