Local deployment can't load local.json if node version >= 4

[ghost]

Using node 4.2.1, local deployment fails to load local.json (/server/index.js) - because fs.constants is not defined.

Package.json states node 4.2.x is required, but https://nodejs.org/docs/v4.2.0/api/fs.html shows that fs.constants is gone.

@nicthemighty, due new design and api changes the app was refactored and now requires node ver. 6.9.x.
