Homebrew-cask: Permission denied when attempting to install new package

[josh-browning]

I recently installed homebrew, and originally had no problems installing new programs. However, today I attempted to install textwranger via

brew install Cask/caskroom/textwrangler

and I got the following error:

Checking out v1.0.1 in /usr/local/Homebrew...
To checkout v1.0.1 in /usr/local/Homebrew run:
'cd /usr/local/Homebrew && git checkout v1.0.1

Error: Permission denied - (/usr/local/Homebrew/Caskroom, /usr/local/Caskroom)Most likely, this means you have an outdated version of Homebrew-Cask. Please run:

brew uninstall --force brew-cask; brew untap phinze/cask; brew untap caskroom/cask; brew update; brew cleanup; brew cask cleanup

If this doesn’t fix the problem, please report this bug:

I then attempted running the suggested command, and received the same error:

I then followed the instructions from github, adding export HOMEBREW_CASK_OPTS="--appdir=~/Applications" to my .bash_profile. I sourced .bash_profile and retried installing, but I got the same error. I'm not sure what else to try.

Thank you so much for your help, and please let me know if you need more info!
