Cannot find module 'generator-jhipster' - node.js

Question

I am trying to load the "generator-jhipster' inside Yeoman as is described on the Yeoman documentation:
http://yeoman.io/authoring/integrating-yeoman.html
var yeoman = require('yeoman-environment');
env.register(require.resolve('generator-jhipster'), 'jhipster:app');
The "generator-jhipster' and "generator-jhipster-entity-audit" modules are installed in node and in the app, in fact, I can use the "generator-jhipster" from the "yo "command without problems, but when I run my node Script, it give me the error:
module.js:549
throw err;
^
Error: Cannot find module 'generator-jhipster'

Any idea about how to solve this error?

Solved.
The jHipster genetator don't have the index.js on the main folder, so, the correct code to invoke it is:
var yeoman = require('yeoman-environment');
var env = yeoman.createEnv();
env.register(require.resolve('generator-jhipster/generators/app'), 'jhipster:app');
