$ brew install caskroom/cask/brew-cask
==> brew cask install caskroom/cask/brew-cask
Error: '/usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask/Casks/brew-cask.rb' does not exist.
Error: nothing to install
Any clue? brew update or brew cleanup did not help..
You don't need to install brew-cask, it is already installed if you have Homebrew. Just run the brew cask command you want.
