Ruby Versions

Puppet requires an MRI Ruby interpreter. Certain versions of Ruby work better with Puppet than others, and some versions are not supported at all. Run ruby --version to check the version of Ruby on your system.

Puppet Enterprise does not rely on the OS’s Ruby version, as it maintains 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.

Ruby version	Puppet 2.6	Puppet 2.7	Puppet 3.x
1.8.5*	Supported	Supported	No
1.8.7	Supported	Supported	Supported
1.9.3	No	No	Supported
1.9.2	No	No	No
1.9.1	No	No	No
1.9.0	No	No	No
1.8.6	No	No	No
1.8.1	No	No	No

* Note that although Ruby 1.8.5 is fully supported on Puppet 2.6 and 2.7, Ruby 1.8.7 generally gives better performance and memory use. To support the large installed base of RHEL5 systems which ship with Ruby 1.8.5, Puppet Labs packages a drop-in replacement Ruby 1.8.7 package. Read the ‘Enterprise Linux and Derivatives’ section of the Installing Puppet guide to learn how to install these packages.

Versions marked as “Supported” are recommended by Puppet Labs and are under extensive automated test coverage. Other versions are not recommended and we make no guarantees about their performance with Puppet.

Prerequisites

Puppet has a very small number of external dependencies:

Dependency	Puppet 2.x	Puppet 3.x
Facter	Required	Required
Hiera	Optional	Required
rgen		Optional

Rgen is only needed if you are using Puppet ≥ 3.2 with parser = future enabled. The official Puppet Labs packages will install it as a dependency.

All other prerequisite Ruby libraries should come with any standard Ruby 1.8.2+ install. Should your OS not come with the complete standard library (or you are using a custom Ruby build), these include:
