What's the number of times the letter "3" appears in:
Q: Puppet Init VirtualEnv Just Once So here's a snippet from my manifest (based on this module: https://github.com/stankevich/puppet-python):
python::virtualenv { $virtualenv_dir:
ensure => present,
version => 'system',
systempkgs => false,
distribute => false,
owner => $user,
group => $group,
}

That works fine when I run puppet apply for the first time. Second time it fails though:
Already using interpreter /usr/bin/python
Traceback (most recent call last):
File "/usr/bin/virtualenv", line 3, in 
virtualenv.main()
File "/usr/lib/python2.7/dist-packages/virtualenv.py", line 938, in main

This is probably because I have a bunch of background processes running that using the Python binary from  virtualenv (Celery workers, uwsgi workers etc).
Is there a way to only init the virtualenv first time? There is no need to run virtualenv command once the directory is created, right?

A: The following class will create a virtual env. "creates" limits the command to only be run if the virtualenv doesn't exist
class virtualenv ( $virtualenv_dir ) {
  package{'python-virtualenv':
    ensure => installed,
  }

  exec{'create_virtualenv':
    creates => $virtualenv_dir,
    command => "virtualenv $virtualen_dir",
    require => Package['python-virtualenv'],
  } 
}

Call the class with the following:
class {'virtualenv':
  virtualenv_dir => '/path/to/virtualenv',
}
