Error running front generator

I’m geeting the error below when I try to create a new Polymer page in Cuba Studio. I started getting this error after I followed the webinar for creating a mobile app using cordova

[23:22:19.679] Project model exported
[23:22:19.848] Error running front generator
throw err;

Error: Cannot find module 'C:\xxxxx\modules\polymer-client\generation\node_modules\@cuba-platform\front-generator\bin\gen-cuba-front'

Hi, try to remove /modules/polymer-client/generation/node-modules and /modules/polymer-client/generation/generators.json

It solved the problem. Thank you.
