createjsonpackage fails, missing defaults.json

Fresh install of plugman
sudo npm install -g plugman

Create new plugin
plugman create --name xyz --plugin_id y.x.z --plugin_version 1.0.0

Attempt to create package.json
plugman createpackagejson xyz/

Returns error
EACCES: permission denied, open '/usr/local/lib/node_modules/plugman/node_modules/cordova-lib/src/plugman/defaults.json'

This isn't actually a permissions error, defaults.json doesn't exist.
