PATH when using puppet apply. RVM buggered.

[Steve Button]

Hi,

I'm using "sudo puppet apply" to get a bunch of puppet code to run for me, but when it runs as root, I notice that the $PATH environment variable is showing as :-

Notice: /Stage[main]/Main/Node[ubuntu-xenial]/Exec[/bin/echo $PATH]/returns: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin

Whereas when I switch to root, I get 

root@ubuntu-xenial:~# echo $PATH

/usr/local/rvm/gems/ruby-2.3.0/bin:/usr/local/rvm/gems/ruby-2.3.0@global/bin:/usr/local/rvm/rubies/ruby-2.3.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/usr/local/rvm/bin

This means that rvm does not work properly, and my Ruby / gem is trying to run as 1.9.3 instead of 2.3.0, leading to lots of errors like :-

Debug: Executing '/usr/local/bin/gem list --local'

Warning: Could not match /usr/local/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>':

Warning: Could not match It seems your ruby installation is missing psych (for YAML output).

Warning: Could not match To eliminate this warning, please install libyaml and reinstall your ruby.

I have tried searching for this error, but haven't found anything yet so I was hoping someone in the community could point me in the right direction!? 

Many thanks,

Steve Button

Later versions of puppet comes with their own supported ruby included[0]

Any specific reason you are using rvm to run puppet?

"Starting with Puppet 4, puppet-agent packages do not rely on the OS’s Ruby version, as it bundles its own Ruby environment. You can install puppet-agent alongside any version of Ruby or on systems without Ruby installed. Likewise Puppet Enterprise does not rely on the OS’s Ruby version, as it bundles its own Ruby environment. You can install PE alongside any version of Ruby or on systems without Ruby installed.  The Windows installers provided by Puppet Labs don’t rely on the OS’s Ruby version, and can be installed alongside any version of Ruby or on systems without Ruby installed."

Hi,

We're not intentionally using rvm to run puppet. We have a RoR application, and we currently want to ensure it runs the correct Ruby version using RVM. For this purpose, we're using the maestrodev/rvm module from the forge.

Thanks for coming back so quickly. 

Steve
