Hello, I am attempting to manage EC2 instances using Puppet's node_aws but everytime I run *~$ sudo puppet node_aws list* I get the following response *Error: undefined method `reject' for #<Symbol:0x00000001c1df0e>* *Error: Try 'puppet help node_aws list' for usage* I have installed Puppet Enterprise Master 3.3.1 on an AWS EC2 Ubuntu 12.04 x64 instance in the ap-southeast-2 region (following the instructions in the first video here<http://puppetlabs.com/blog/install-puppet-enterprise-ec2-our-new-guide> to produce an installation answer file<https://github.com/elcollie/publicscripts/blob/master/puppet.master.answer> ) I have also installed Ruby 2.0.0p353, Gem version: 2.1.11 and run the Cloud Provisioner install as outlined here<https://forge-staging-web.puppetlabs.com/puppetlabs/cloud_provisioner/1.0.4> . I also configured my ~/.fog file *:default:* * :aws_access_key_id:MYKEY* * :aws_secret_access_key:MYSECRETKEY* I successfully ran *sudo puppet agent -t* on the server to have its agent check and appear in the console. Any help would be greatly appreciated. Col -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
