I'm trying to install grunt, but no luck.
npm install -g grunt-cli --registry http://registry.npmjs.org/
gives this error:
npm ERR! registry error parsing json
npm ERR! Darwin 14.3.0
npm ERR! argv "node" "/usr/local/bin/npm" "install" "-g" "grunt-cli" "--registry" "http://registry.npmjs.org/"

What could be wrong?
