Could not evaluate: undefined method `map'

[djjudas21]

Every puppet run, my Puppetmaster prints out an error for each Forge module that has been installed with rcoleman/module.

Error: /Stage[main]/Uob_puppet::Forgemodules/Module[saz/timezone]: Could not evaluate: undefined method `map' for #<Puppet::Node::Environment:0x7f698db18c78>

It has been doing this for sometime but I assumed it was related to PUP-2882 which was fixed today in Puppet 3.7.0, but this hasn't fixed the problem. Please could you investigate?

The problem occurs with v0.0.3 of your module and several versions of Puppet, including v3.6.x and 3.7.x.

Thanks, Jonathan

I get this too, puppet 3.6.2, appears to not matter which module it is but reproducible with razorsedge/network fwiw.

Some additional confirmations:

• Broken under Puppet 3.7.2
• Working under 3.4.3

Here is the output from a delcaration for module { 'puppetlabs/ntp': ensure => installed }:

==> default: /etc/puppet/modules/puppet_module/lib/puppet/provider/module/forge.rb:40: warning: class variable access from toplevel
==> default: Error: /Stage[main]/Main/Module[puppetlabs/ntp]: Could not evaluate: undefined method `map' for production:Puppet::Node::Environment

The corresponding line appears to be:

    @@module.list.map do |module_path, modules|

from the function block:

  def self.installed
    @@module.list.map do |module_path, modules|

      modules.map do |mod|
        #puts mod.inspect
        {
          :name => mod.forge_name,
          :ensure => mod.version,
          :modulepath => module_path,
          :provider => :puppet_module,
        }
      end

    end.flatten
  end

Had a quick look into Puppet faces, it appears that even though the Puppet face for modules is still 1.0.0, there is a change between Puppet 3.4.3 and 3.7.2 that breaks the face.

I'll lodge a bug on the Puppet tracker, and am testing a pull request for this module to both address the issue and specify an explicit dependency on version 1.0.0 of the module face (currently :current).

I have lodged a bug on the Puppet ticket system for the original issue: https://tickets.puppetlabs.com/browse/PUP-3563

I also has the same error on puppet v4.2.2

[go8ose]

Would it be possible for this provider to handle both aspects of this face? If it finds a list of modules, it uses it's existing code. If an exception is thrown on the map access, it tries to process the returned value as a hash?

I have almost no knowledge of ruby, my attempts to try this out have failed.

Looks like module is not working anymore on Puppet 4.
