Ruby Question

Bundle won't recognize installed gems

I'm trying to run "bundle install --without production" with this as the result:

bundle install --without production

An error occurred while installing rack (2.0.1), and Bundler cannot continue.
Make sure that `gem install rack -v '2.0.1'` succeeds before bundling.

So multiple times, I have run

gem install rack -v 2.0.1

with the result:

Successfully installed rack-2.0.1
Parsing documentation for rack-2.0.1
Done installing documentation for rack after 3 seconds
1 gem installed

I call "rbenv rehash" and retry bundle install and the exact same error message shows up. When I call "ruby -v", it shows I have ruby version 2.3.1. How do I get the bundler to recognize that I have updated Ruby? Is this a problem with Bundler? Am I saving the gems to the wrong place? I have searched similar questions for hours and none of the solutions worked.

The error says you need Ruby version of 2.2.2 or greater. Can you check which version you have? ruby -v in the command line should work

EDIT: Looks like you just had to restart your terminal window...
