Homebrew error installing tomcat

Question

After installing tomcat on Os x El Capitan using Homebrew I have received the following Warning:

your HOMEBREW_PREFIX is set to /usr/local but HOMEBREW_CELLAR is set to /usr/local/Cellar. Your current HOMEBREW_CELLAR location will stop you being able to use all the binary packages (bottles) Homebrew provides. We recommend you move your HOMEBREW_CELLAR to /usr/local/Cellar which will get you access to all bottles."

The command brew services list shows no services installed. Printenv doesn't show any homebrew variable It's not clear to me what should I do.

I also encountered this problem, in the end of the page to get accurate help,

brew bundle dump

rm -rf /usr/local/Homebrew/Cellar

brew bundle

Answer 2

I have received a similar warning when I tried to do a brew update. It did not allow me to update. All I have done to resolve it was do a brew update in going to the /usr/local/Cellar directory. From what I understand HOMEBREW_REPOSITORY path was modified or went missing when the OS was updated. After the brew update, the message said Migrated HOMEBREW_REPOSITORY to /usr/local/Homebrew! Homebrew no longer needs to have ownership of /usr/local. If you wish you can return /usr/local to its default ownership with: sudo chown root:wheel /usr/local

This got me back to my normal brew usage with out a problem.
