Ember cli not giving me latest

Correct me if I’m wrong, but running ember init is supposed to give me the latest ember 3.4.x everything if I’ve updated ember-cli to 3.4.2, yes? I’ve updated global ember-cli to 3.4.2. running ember --version only ever shows ember-cli: 3.1.4, and running init only ever gives me 3.1.4, and ember-source and -data aat 3.1.0 in package.json.

What on earth am I doing wrong here? Thanks.

Ok so complete uninstall of ember-cli and ember-cli-update, reinstall and check on perms / ownership on global node modules, as well as update of node to 8.12 is now working. Leaving this here in case it’s helpful to others.
