I have rvm installed on my PC with the default ruby gemset being 2.4.1
rvm list
ruby-2.4.0 [ x86_64 ]
=* ruby-2.4.1 [ x86_64 ]
ruby-2.6.3 [ x86_64 ]
# => - current
# =* - current && default
# * - default
I want to install rails 5 however sprockets
fails to install requiring 2.5 ruby. However rails 5 should work with any ruby above 2.2.2:
gem install rails -v 5.1.4
Fetching: activesupport-5.1.4.gem (100%)
Successfully installed activesupport-5.1.4
Fetching: actionview-5.1.4.gem (100%)
Successfully installed actionview-5.1.4
Fetching: actionpack-5.1.4.gem (100%)
Successfully installed actionpack-5.1.4
ERROR: Error installing rails:
sprockets requires Ruby version >= 2.5.0.
I don't care about the rails 5 version. The newer the better, but all versions do give me the errors
Any idea why this might happen?

The latest (4.0.0) version of sprockets really requires ruby >= 2.5.0
. Check it here
Is gem 'sprockets'
in your Gemfile
set to a specific version?
To manually change version of sprockets add the line bellow to your Gemfile
gem 'sprockets', '~> 3.7.2'
If you do not have a Gemfile yet try direct installation.
gem install sprockets -v 3.7.2

For those that are experiencing this without having it explicitly specified in the gemfile, another workaround is to install the previous version manually:
gem install sprockets -v 3.7.2

Rails 5 may only require Ruby => 2.2.2
but if you don't version gems in your Gemfile
it will always pull down the latest version of the gems. A later gem version then might need a higher version of Ruby.
This however has nothing to do with rails!
Also you might have a Problem with Ruby 2.4.1 using it with Rails 5.1.4
Which Ruby on Rails is compatible with which Ruby version?
