I'm trying to install Rails 5 on my Mac (El Capitan).

When I type

gem install rails

I get this error message:

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

When I check my Ruby version with Rbenv:

rbenv global
2.3.1

however when I check my Ruby version like this:

ruby -v

I get

ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14]

how can I fix this, so when I want to install rails 5, it's using Ruby 2.3.1

Thanks for your help,

Anthony

@Sravan how are commands for a different ruby version manager than they're using going to help? – j-dexx Oct 17 '16 at 14:22
yeah sry, removed that. – Sravan Oct 17 '16 at 14:23
Try setting the shell ruby by: `rbenv shell 2.3.1` – max Oct 17 '16 at 15:14
Have you run `rbenv init` as well? It could be that rbenv is not properly integrated into your shell. https://github.com/rbenv/rbenv#how-rbenv-hooks-into-your-shell – max Oct 17 '16 at 15:18
this might be a silly question, but have you got .ruby-version in your project's top level directory? And that it points to the correct ruby version? – jaydel Oct 17 '16 at 16:01
I solved the issue by running 'rbenv local 2.3.1' – Toontje Oct 18 '16 at 06:27
