How to fix "Your Ruby version is 2.5.3, but your Gemfile specified 2.5.1" deploying the AWS eb?

Issue: I am having issues deploying app to AWS EB and every remedy I have found on SO and google have not helped my situation.

I installed the AWS EB command line and looking to deploy an app I have built to there but i keep getting this error after attempts to resolve it:

ERROR   [Instance: i-065ec77b2c530362b] Command failed on instance. Return code: 18 Output: (TRUNCATED)...g: the running version of Bundler (1.16.2) is older than the version that created the lockfile (1.17.2). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.
Your Ruby version is 2.5.3, but your Gemfile specified 2.5.1. 
Hook /opt/elasticbeanstalk/hooks/appdeploy/pre/10_bundle_install.sh failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.
2018-12-21 08:51:28    INFO    Command execution completed on all instances. Summary: [Successful: 0, Failed: 1].

The app was initially built with 2.5.1 but I switched it to 2.5.3 today so I can put it onto AWS. (I have both of these ruby versions with rbenv)

I have done:

• Set ruby '2.5.3' in Gemfile
• bundle update
• bundle install
• gem install bundler
• gem update bundler
• deleted gem lock file and bundle updated
• ./bin/spring stop (spring not running)

ruby -v is ruby 2.5.3p105 (2018-10-18 revision 65156) [x86_64-linux] (this is local only, I have rbenv global set to 2.5.1, but I don't believe this is an issue as the error states i's the gemfile)

I have done rbenv rehash after updating or installing bundle

bundle update --ruby

Gemfile.lock shows 2.5.3

bundle env shows:

RUBY VERSION
   ruby 2.5.3p105

BUNDLED WITH
   1.17.2

Thank you for your time and reading this and your help!!!

NAIL IN THE COFFIN:

I just took the copy of my app i created before updating to the new ruby and tried to deploy it and got this:

Your Ruby version is 2.5.3, but your Gemfile specified 2.5.1. 
Hook /opt/elasticbeanstalk/hooks/appdeploy/pre/10_bundle_install.sh failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.
2018-12-21 11:04:39    INFO    Command execution completed on all instances. Summary: [Successful: 0, Failed: 1].

.....this is which 2.5.1 set globally and locally

What other options do I have? Delete and re install rbenv? Make a new app and copy everything over except the gemfile? I'm out of options and ideas it seems like

UPDATE:

I had no clue that AWS EB was based off my git commits and i never updated them before trying... ( wow ) and now i don't receive the ruby version error...

So now i don't get the version error but I do get this error:

Since this error is different from the original question, I have created a new one here: Deploying with AWWS EB but with erors
