Git Push to Rails Production Gives Response Your Ruby version is 1.9.3, but your Gemfile specified 2.2.2 When Ruby Version is 2.2.2

Question

I have seen this error all over the place, but none of the solutions I have found have helped to fix the issue. I am developing a rails app locally on a Mac and have set up a droplet on DigitalOcean to push the app to. My droplet is running Ubuntu 14 and i am deploying using a Git post-receive hook. This is the hook:

#!/bin/bash

GIT_DIR=/home/xxx/yyy_production
WORK_TREE=/home/xxx/yyy
export XXX_DATABASE_USER='xxx'
export XXX_DATABASE_PASSWORD='12345'

export RAILS_ENV=production
. ~/.bashrc

while read oldrev newrev ref
do
    if [[ $ref =~ .*/master$ ]];
    then
        echo "Master ref received.  Deploying master branch to production..."
        mkdir -p $WORK_TREE
        git --work-tree=$WORK_TREE --git-dir=$GIT_DIR checkout -f
        mkdir -p $WORK_TREE/shared/pids $WORK_TREE/shared/sockets $WORK_TREE/shared/log

        # start deploy tasks
        cd $WORK_TREE
        bundle install
        rake db:create
        rake db:migrate
        rake assets:precompile
        sudo restart puma-manager
        sudo service nginx restart
        # end deploy tasks
        echo "Git hooks deploy complete"
    else
        echo "Ref $ref successfully received.  Doing nothing: only the master branch may be deployed on this server."
    fi
done

This is the output I get when I push:

remote: rake aborted!
remote: Bundler::RubyVersionMismatch: Your Ruby version is 1.9.3, but your Gemfile specified 2.2.2

I don't understand this at all, as I have installed ruby 2.2.2 and selected it using RVM. When I log on to the Ubuntu machine using ssh, I don't get any errors at all running bundler. Yet this is what it does when I run using my hook. I've been fighting with this for several days. Any help is greatly appreciated.

Just some additional info:

On both your droplet and your mac, remove Gemfile.lock, make sure ruby -v responds with version 2.2, and do a bundle update.

These steps should reset everything. If they don't work, do a spring stop and reinstall bundler binstubs (if you use these tools).

Good luck!
