Librarian Puppet - Undefined method `map' for nil:NilClass (default: NoMethodError)

Question

While Provisioning Vagrant VM with arpitaggarwal/tomcat module from Puppet Forge using librarian-puppet works for me with content in Puppetfile as follows:

Puppetfile :

forge "http://forge.puppetlabs.com"
mod "puppetlabs/apt"
mod 'tomcat', :git => 'https://github.com/arpitaggarwal/tomcat.git'

And, when I edited PuppetFile content as:

forge "http://forge.puppetlabs.com"
mod "puppetlabs/apt"
mod "arpitaggarwal/tomcat"

I got an error:

Any idea how can I fix it?

Answer 1

Can you detail how you install librarian-puppet

I have a script to install it (based on this one ) and it installs fine with the following

manifests/init.pp

class { 'tomcat':  }

Puppetfile

forge "http://forge.puppetlabs.com"

mod "puppetlabs/apt"
mod "arpitaggarwal/tomcat"

output of vagrant up

Tomcat was installed and on the VM

vagrant@precise64:~$ librarian-puppet version
librarian-puppet v1.5.0
vagrant@precise64:~$

Previous Answer I think in newer version of librarian, you need to use forge "https://forgeapi.puppetlabs.com"
