Bundler Trying To Run Under Wrong Version of Ruby - ruby-on-rails

Question

I have a rails site, which I deploy via ssh using a git post-receive hook. When I ssh into the server and run bundle install it runs correctly under the specified ruby version of 2.2.2. However, when I push to the server from my local machine and it hits the 'bundle install command', I get the following:
hooks/post-receive: /usr/local/bin/bundle: /usr/bin/ruby1.9.1: bad interpreter: No such file or directory
I can't find for the life of me why it is pointing to ruby1.9.1. This directory does not exist. I do see a directory for ruby2.3 in that directory, but not ruby2.2.2 which is the correct directory. Something is quite fouled up, but I can't figure how to fix it. Anyone seen anything like this?
UPDATE: Here is my post-receive hook, as per the request below...
#!/bin/bash
GIT_DIR=/home/deploy/www_production
WORK_TREE=/home/deploy/www
export MGOTS_DATABASE_USER='user'
export MGOTS_DATABASE_PASSWORD='pass'
export RAILS_ENV="production"
. ~/.bash_profile
while read oldrev newrev ref
do
if [[ $ref = refs/heads/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
rake requests:cleanup
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
UPDATE: For the sake of clarity, as the answer points to the correct place to find the answer, but doesn't state it exactly, I am posting my updated hook file here. You can see the difference between this one and the one above, and that is what solved the problem. Please note that the path to the rvm directory can be found by typing the command: which rvm - that's the one you want to point to.
#!/bin/bash
GIT_DIR=/home/deploy/www_production
WORK_TREE=/home/deploy/www
export MGOTS_DATABASE_USER='user'
export MGOTS_DATABASE_PASSWORD='pass'
export RAILS_ENV="production"
export RUBYGEMS_GEMDEPS="/home/deploy/.rvm/ruby-2.2.2#www/gems"
. ~/.bash_profile
[[ -s "/usr/share/rvm/bin/rvm" ]] && source "/usr/share/rvm/bin/rvm"
while read oldrev newrev ref
do
if [[ $ref = refs/heads/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
rake requests:cleanup
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

Answer 1

You need to load RVM functions to the shell script. link
Or just switch to Rbenv :)

Answer 2

First, set your default ruby to use the version 2.2.2
Are you using RVM? For RVM its: rvm use --default 2.2.2
