puppet cannot find class from installed module apache

This is probably just a basic question, but I can't find a solution. I set up an environment where I want to use the apache module given by puppetlabs.
My puppet version is 3.7.2
tree of my directory:

.
├── environments
│   └── test
│       ├── environment.conf
│       ├── manifests
│       │   └── site.pp
│       └── modules
│           ├── apache
│           │   └── manifests
│           │       ├── init.pp
│           │       └── vhost_basic.pp
│           └── update
│               └── manifests
│                   └── init.pp
└── Vagrantfile

my provisioner inside Vagrantfile looks like this:

config.vm.provision :puppet do |puppet|  
  puppet.environment_path = "environments"  
  puppet.environment = "test"  
  puppet.options = ['--verbose']
end

my site.pp:

 Exec { path => [ "/bin/", "/sbin/" , "/usr/bin/", "/usr/sbin/" ] }
 include update

 node 'localhost' {
   class { 'apache': }             # use apache module
   apache::vhost { 'example.com':  # define vhost resource
     port    => '80',
     docroot => '/var/www/html'
   }
 }

inside the apaches (directory) init.pp I only have include apache. And I installed the apache module via puppet module install puppetlabs-apache. And it's also stored in home/user/.puppet/modules. I also installed the module via sudo (since I read somewhere that it makes a difference..). But when I run vagrant provision it says me:

 ==> default: Running provisioner: puppet...
 ==> default: Running Puppet with environment test...
 ==> default: Error: Evaluation Error: Error while evaluating a Resource Statement, Could not find declared class apache at /tmp/vagrant-puppet/environments/test/manifests/site.pp:16:3 on node localhost

What am I missing here?

EDIT:
the result of puppet config print |grep path is:

path = none  
environmentpath =   
basemodulepath = /home/user/.puppet/modules:/usr/share/puppet/modules  
modulepath = /home/user/.puppet/modules:/usr/share/puppet/modules  
factpath = /home/user/.puppet/var/lib/facter:/home/user/.puppet/var/facts

Solution

You environment.conf is not correct, as you installed the modules locally they will be shared in your VM under the /vagrant directory so you should reference this instead. (they are shared in your /etc/puppet directory when you indicate the puppet.modules path in your puppet provisioner block)

However what I suggest is to add a simple shell provisioner which will install the modules for you (and manage the sudo part) - In your vagrantfile (before the puppet provisioner)

config.vm.provision :shell, path: "/path/to/script.sh"

In your script.sh

#!/bin/bash

puppet module install puppetlabs-apache --version 1.10.0

This will install the modules in /etc/puppetlabs ... so you can reference this in your environment.conf

modulepath = /etc/puppetlabs/code/environments/production/modules:$basemodulepath
