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 was getting:

$ brew link node
Error: No such keg: /usr/local/Cellar/node
$ brew link node@8
Warning: node@8 is keg-only and must be linked with --force

That command helped to get everything working again:

brew link --overwrite --force node@8
