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.
登录后复制
那么就需要重新安装virtualbox，命令：
brew cask reinstall virtualbox
登录后复制
登录后复制
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).
登录后复制
那么，就需要网上拉日志，找到：
warning! found the following active virtualbox processes:
登录后复制
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
登录后复制
然后再重新安装：
brew cask reinstall virtualbox
登录后复制
登录后复制
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：
~ brew cask reinstall virtualbox ==> caveats to install and/or use virtualbox you may need to enable its kernel extension in: system preferences → security & privacy → general ... ==> running installer for virtualbox; your password may be necessary. ==> package installers may write to any location; options such as --appdir are ignored. installer: package name is oracle vm virtualbox installer: installing at base path / installer: the install failed (the installer encountered an error that caused the installation to fail. contact the software manufacturer for assistance.) ==> purging files for version 6.0.10,132072 of cask virtualbox error: failure while executing; `/usr/bin/sudo -e -- env logname=gary user=gary username=gary /usr/sbin/installer -pkg /usr/local/caskroom/virtualbox/6.0.10,132072/virtualbox.pkg -target /` exited with 1. here's the output: installer: package name is oracle vm virtualbox installer: installing at base path / installer: the install failed (the installer encountered an error that caused the installation to fail. contact the software manufacturer for assistance.) follow the instructions here: https://github.com/homebrew/homebrew-cask#reporting-bugs /usr/local/homebrew/library/homebrew/system_command.rb:111:in `assert_success' ...
