New Ubuntu install, trying to install Ruby 2.3.1 alongside 2.5.0 for another project

So I've just installed Ubuntu, installed Ruby on Rails (the latest) based on the article here: https://gorails.com/setup/ubuntu/17.10

I can run rails just fine on a brand new application; however, I'm trying to run an application that requires Ruby 2.3.1. If I go to the rails directory of that application and try to do bundle install, I get:

Your Ruby version is 2.5.0, but your Gemfile specified 2.3.1

I tried to install Ruby 2.3.1 using rbenv install 2.3.1 but I get an error log that looks like a memory stack or something. Nothing that seems to be of any help.

How can I go about installing Ruby 2.3.1 without screwing up my other installation of 2.5.0 since this isn't working? This is the error log I get when trying to install 2.3.1 using rbenv.

~/apps/smartadmin(master*) » rbenv install 2.3.1                                        4:33PM/01.11

Before I got too ahead of myself and trying to install rvm and using rvm to install 2.3.1, I wanted to get some advice here. I've already had to spin up a fresh VM after getting into a big mess with this.

According to this: https://bugs.ruby-lang.org/issues/14076 The problem is gcc version (gcc-7 in Artful). So we need to install gcc-6 in Artful.

Download gcc-6.4 built for Artful from: https://packages.ubuntu.com/artful/gcc-6

Install the .deb file (either by clicking on the file or using terminal command).

Then try the solution proposed in the first link above. CC=/usr/bin/gcc-6 rbenv install 2.3.1

Then, you should have 2.3.1 installed on Artful. Good luck!
