The most interesting thing for me is that jhipster lives in a denial - isn’t detecting node, although being executed by node.




checkNode tries to detect node using node -v, looks like there are something with your environment that makes the those commands node -v and npm show generator-jhipster version return incorrectly.


A fix would be to use process.versions.node instead of node -v like https://github.com/jhipster/generator-jhipster/blob/1e43348302c34855639d73587c3761d25a61a957/cli/jhipster.js#L25


and use latest-version package instead of npm show generator-jhipster version

I couldn’t reproduce:


npm -g uninstall generator-jhipster
npm install generator-jhipster@6.9.1
npx jhipster



Generated the project correctly.


$ node -v
v12.16.1
$ npm -v
6.13.4
