bundler install getting "i18n requires Ruby version >= 1.9.3"

Question

How can I correct this "i18n requires Ruby version >= 1.9.3" I get when I run "bundler install"?

Background: Need to use ruby 1.8.7 on dreamhost, so have targeted Rails v3.2 for this.

Command Line

Gregs-MacBook-Pro:weekends Greg$ ruby -v
ruby 1.8.7 (2013-12-22 patchlevel 375) [i686-darwin14.1.0]

Gregs-MacBook-Pro:weekends Greg$ bundler -v
Bundler version 1.9.2

An error occurred while installing i18n (0.7.0), and Bundler cannot continue.
Make sure that `gem install i18n -v '0.7.0'` succeeds before bundling.

Gem File

gem 'rails', '3.2' # Dreamhost is Ruby 1.8.7. Rails 3.2 requires at least Ruby 1.8.7
gem 'sqlite3'
gem 'haml'
gem 'haml-rails'
gem 'omniauth-google-oauth2'
gem 'google-api-client', :require => 'google/api_client'
gem 'jquery-rails'
gem 'figaro'
gem 'rest-client'

Solution

You could try to downgrade I18n's version to 0.6.11, because that seems to be the latest version that does not require Ruby 1.9.3. To do so add this to your Gemfile

gem 'i18n', '0.6.11'

and try to run bundle install again.

Furthermore, I suggest upgrading your Ruby and Rails versions. They are both outdated. At least you could try to run Rails 3.2 with a version of Ruby that allows the new syntax. Otherwise, you will face this kind of problems with many other gems too and - more important - you will not be able to install all the security fixes there were released during the last years.

I'll try this - background is I need to ruby 1.8.7 on dreamhost (unless I upgrade to a VPS, costs more), so have targeted Rails v3.2 for this

I think it is bad decision to trade the low cost for a VPS against the risk of well known security issues in outdated software stacks. You might want to consider hosting on Heroku then, they have a free plan.

good point @spickermann - plus I'm still having trouble trying to replicate this older stack too...
