Installing 2.2.1 requires ruby 2.2.2 about librarian-puppet

As a workaround you can install activesupport version 4.2.5.

activesupport 5.0.0 is now released. So now I'm seeing this issue with installing 2.2.1, didn't see it a few weeks ago despite the age of this ticket, but I presume that is because when this ticket was opened it was just a beta.

As a pointer to others who might be running into this issue. Just installing activesupport 4.2.5 (as mentioned in a previous comment) didn't help me. You need to install all the dependencies for librarian-puppet individual and use --ignore-dependencies on any of the ones that are in the chain that requires activesupport. You might be able to get around that with --minimal-deps but the version of gem I had didn't have that option.

But replacing: gem install librarian-puppet -v 2.2.1 with the following set of commands resolved the problem for me:

gem install activesupport -v 4.2.6
gem install activemodel -v 4.2.6
gem install faraday -v 0.9.2
gem install multi_json -v 1.12.1
gem install her -v 0.6.8 --ignore-dependencies
gem install puppet_forge -v 1.0.5 --ignore-dependencies
gem install librarianp -v 0.6.3
gem install rsync -v 1.0.9
gem install librarian-puppet -v 2.2.1 --ignore-dependencies

This is of course really ugly and prone to breakage as other dependency versions upgrade. The specific versions I've chosen here match what I was getting before activesupport released 5.0.0. I'm also not installing any development dependencies. So if you want those use gem dependency to figure them out and add them to the list.

I think this should be solved by voxpupuli#1
