Problem

When you try to apply the puppet configuration into a vagrant box and using systemwide rvm installation (if you follow the instructions here), you have the following error:

vagrant@precise64:~$ sudo puppet apply --verbose puppet/manifests/site.pp
/usr/local/rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find puppet (>= 0) amongst [] (Gem::LoadError)

Solution

Use rvmsudo instead of sudo to make sure that the paths are correct:

vagrant@precise64:~$ rvmsudo puppet apply --verbose puppet/manifests/site.pp
