Puppet: stdlib installed but not available in namespace?

Question

as a puppet newbie, I have a problem including the stdlib plugin

I would like to use stdlib's file_line, thus I try to include stdlib and call it

class service_mon
{
  include stdlib
  file_line 
  {
    "${name}_services": path=> ...
  }
}

However, I get an error message, that stdlib cannot been found

err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class stdlib for my.node.name at /etc/puppet/workspace/dev/src/modules/mymanifest/manifests/deploy.pp:87 on node my.node.name

which makes me wonder since stdlib should be installed(?) ...or?

puppet module install puppetlabs-stdli

puppet module list
/etc/puppet/modules
└── puppetlabs-stdlib (v4.2.2)
/usr/share/puppet/modules (no modules installed)

puppet config print modulepath
/etc/puppet/modules:/usr/share/puppet/modules

So, I guess in principle all necessary files are 'there' but how can I convince Puppet to include stdlib as well?

Did you ever solve this? I seem to be running into the exact same issue. :-/ — Christopher, Nov 14 '14 at 23:32
Hi Christopher - unfortunately I have not yet managed to get it running satisfactorily -- and 'postponed' it by using a small shell script to do the work I hoped I could solve with stdlib :-/ — THX, Jan 07 '15 at 10:19
I had to explicitly provide the modules path using modulePath option in my puppet file apply command in terminal: ```bash puppet apply 0-the_sky_is_the_limit_not.pp --modulepath /etc/puppet/code/modules ``` — MosesSoftEng, Nov 11 '22 at 06:17

Puppet modules do not work like java modules - include stdlib would only make sense if there actually was a class stdlib in the module which did something useful, which is not the case.

Note: Many Puppet modules do have such a class that serves as the central entry point, but stdlib is a notable exception.

You can use the parser functions from stdlib by just calling them. As for the types, those just become available to Puppet if

the module is installed inside your $modulepath and
you have pluginsync enabled on your agents

You can use file_line without any ado.
