PuPHPet Vagrant Debian - Won't change provisioned Node.js version -

i want change node.js version provisioned custom machine (debian75-x64) v0.12.15 v4.5.0. config.yml was:

nodejs:     install: '1'     settings:         version: '0.12'     npm_packages:         - bower         - gulp         - grunt-cli         - browser-sync 

and changed to:

nodejs:     install: '1'     settings:         version: '4'     npm_packages:         - bower         - gulp         - grunt-cli         - browser-sync 

then ran vagrant provision, , check if new node version has been installed. unfortunately keep getting

$ node --version v0.12.15 

no matter restarting machine , provisioning again. missing else?

citing juan in https://github.com/puphpet/puphpet/issues/2420:

inside vm delete /.puphpet-stuff/nodesource , try again.

it worked.
