AWS Rails install fails: activesupport requires Ruby version >= 2.2.2

I am installing rails 5 on aws. I have installed rvm and ruby. Ruby version I installed is 2.3.1. I have done bundle install.

Now I am trying to install rails 5 by using command - 'sudo gem install rails --version 5.0.0'

But I am getting error 

ERROR:  Error installing rails:
        activesupport requires Ruby version >= 2.2.2.

rvm list

=* ruby-2.3.1 [ x86_64 ]

Complete log on running command - 'sudo gem install rails --version 5.0.0'

ERROR:  Error installing rails:

Why it is showing ruby version required >= 2.2.2 ? What should I do here?

This worked for me when I updated my Ruby version to the latest 3.2.2, the latest available (presently). Use "rbenv install --l" to check for the latest version.

brew install rbenv ruby-build rbenv init eval "$(rbenv init - zsh)" rbenv install --l rbenv install 3.2.2 rbenv global 3.2.2

Since you are using rvm, you should install gems for the current user. That means without sudo.

gem install rails --version 5.0.0
