Ionic serve error: unreadable "refresher"

I don’t know what’s going on with ionic serve, its not building and its throwing some weird errors:

      throw er; // Unhandled stream error in pipe.
Error: www/lib/ionic/scss/ionic:30: error: file to import not found or unreadable: "refresher"

my gulp file is fine, same as default one, i just added that errLogToConsole
I am on latest Ionic versions, 1.4 alpha 6.

Run through some of the solutions in this topic and see if they help:
