Capistrano bash: bundle: command not found even has been installed - ruby-on-rails

Question

Hi guys i have problem to deploy my rails app to production server. Actually i have install bundle in server via gem install bundler. Unfortunately when i typed cap production deploy it becomes like this:
** [out :: server url] bash: bundle: command not found
command finished in 772ms
*** [deploy:update_code] rolling back
* executing "rm -rf /home/deployer/crawler/releases/20180326063414; true"
servers: ["server url"]
[server url] executing command
command finished in 833ms
failed: "rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell 'ruby-2.2.1' -c 'cd /home/deployer/crawler/releases/20180326063414 && bundle install --gemfile /home/deployer/crawler/releases/20180326063414/Gemfile --path /home/deployer/crawler/shared/bundle --deployment --quiet --without development test'" on server url
it says bash: bundle: command not found. I typed bundle --version the output is:
Bundler version 1.16.1
here is my gemfile
group :development do
gem 'capistrano', '~>2.15.4'
gem 'rvm-capistrano', '1.4.1', require: false

My question is, why that capistrano still asking my bundle command not found if i trace it failed in rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell 'ruby-2.2.1' -c 'cd /home/deployer/crawler/releases/20180326065919 && bundle install --gemfile /home/deployer/crawler/releases/20180326065919/Gemfile --path /home/deployer/crawler/shared/bundle --deployment --quiet --without development test'?
