After installing yarn (0.20.3) for the very first time, yo (1.8.5), generator-jhipster with yarn global add generator-jhipster@4.0.6 and extend the $PATH as mentioned by the installation guide, the new version of jhipster istn't used. Instead, the jhipster 3.12.1 is found, which was always installed by node/npm.
yo is taken from $HOME/.config/yarn/global/node_modules/.bin
jhipster 4.0.6 is installed in $HOME/.config/yarn/global/node_modules/generator-jhipster
What should I do, that yo takes the latest jhipster installation?
