I have an existing jhipster app that I am trying to keep up to date with the generator. I successfully updated the app to 3.1.0 generated code and would now like to update to 3.2.0. I have installed the 3.2.0 generator and can create a new app with that version (generator shows version 3.2.0 when I run "yo jhipster"). However when I run "yo jhipster" in the root of my existing app, I the generator reports that it is using jhipster 3.1.0.
This is a known issue, please read comments in this pull request https://github.com/jhipster/generator-jhipster/pull/3562
Try deleting node_modules folder of your project before running yo jhipster
