Can't `brew link` an unlinked keg

Question

$: which node
$: node
-bash: node: command not found
$: brew install node
Error: node-0.6.18 already installed
$: brew doctor
Error: You have unlinked kegs in your Cella         


        

Answer 1

I personally had to work some sudo chmod magic for node files that were not writable. Brew didn't take care of them by default even after --force was enabled.
