Dupilicate declaration for requirement file

[samho]

I try to do below steps:

1. Get the requirement file from master server, and save to /tmp/ directory
2. Create the virtualenv and install package with the requirement file which has been saved in /tmp directory.

But when I try to so, there is always an error appeared, it shows as below:
Error: Failed to apply catalog: Duplicate declaration: File[/tmp/requirement.txt] is already declared in file /etc/puppet/modules/general/manifests/init.pp:7; cannot redeclare at /etc/puppet/modules/python/manifests/requirements.pp:98

it means "path parameter" of file resource and "requirements parameter" of python::virtualenv cannot be same, but this is not make sense, please fix it.

Just FYI, tested it with the following manifest and could not reproduce the bug:

class { 'python':
  version    => 'system',
  dev        => true,
  virtualenv => true,
}

file { '/tmp/requirements.txt':
  ensure  => present,
  content => '# nothing',
}

python::virtualenv { '/var/www/project1':
  ensure       => present,
  version      => 'system',
  requirements => '/tmp/requirements.txt',
  systempkgs   => true,
}

python::requirements { '/tmp/requirements.txt':
  virtualenv => '/var/www/project1',
}

Looks like this line https://github.com/stankevich/puppet-python/blob/bd1e2cf705589448dc08f76ed080cae5efce99e4/manifests/requirements.pp#L105 prevents this error.

I'm glad this post is here because I was running into a similar problem. The post above seems like a non-intuitive way to use the module. Why does the python::requirements class need to be invoked along with python::virtualenv? It seems like both statements would accomplish populating a virtualenv independently or am I misunderstanding something?

@rcmachado Thank you for the explanation :)
