Capistrano and Bundler problem - bundle: not found - ruby-on-rails

Question

I keep getting the following error when trying to deploy my app with the bundle/install option:
failed: "sh -c 'cd /home/deploy/swamp/releases/20110903003336
&& bundle install --gemfile /home/deploy/swamp/releases/20110903003336/Gemfile
--path /home/deploy/swamp/shared/bundle --deployment --quiet
--without development test'" on 12.345.678.98
**Update - looks like I missed an error:
[err :: 12.345.678.98] sh: bundle: not found
I've tried this in my deploy.rb:
require "bundler/capistrano"
and I've tried this:
namespace :bundler do
task :create_symlink, :roles => :app do
shared_dir = File.join(shared_path, 'bundle')
release_dir = File.join(current_release, '.bundle')
run("mkdir -p #{shared_dir} && ln -s #{shared_dir} #{release_dir}")
end
task :bundle_new_release, :roles => :app do
bundler.create_symlink
run "cd #{release_path} && bundle install --without test"
end
end
after 'deploy:update_code', 'bundler:bundle_new_release'
I've also moved my bundle to the vendor path with this:
bundle install --path vendor/bundle
I don't think it's a permissions problem, because I can log in manually with deploy and bundle install directly on the server no problem. Here is the entire deploy.rb file:
require "bundler/capistrano"
set :application, "swamp"
set :domain, "12.345.678.98"
set :repository, "git#github.com:***/**.git"
set :deploy_to, "/home/deploy/#{application}"
set :rails_env, 'production'
set :branch, "master"
role :app, domain
role :web, domain
role :db, domain, :primary => true
set :deploy_via, :remote_cache
set :scm, :git
set :user, "deploy"
set :runner, "deploy"
ssh_options[:port] = ****
set :use_sudo, false
after "deploy", "deploy:cleanup"
namespace :deploy do
desc "Restarting mod_rails with restart.txt"
task :restart, :roles => :app, :except => { :no_release => true } do
run "touch #{current_path}/tmp/restart.txt"
end
[:start, :stop].each do |t|
desc "#{t} task is a no-op with mod_rails"
task t, :roles => :domain do ; end
end
end
task :after_update_code do
run "ln -nfs #{deploy_to}/shared/config/database.yml #{release_path}/config/database.yml"
end

I found the solution here:
http://www.pastbedti.me/2011/06/change-path-environment-with-rails-and-capistrano/
In you config/deploy.rb add the following snippet
set :default_environment, {
'PATH' => "/opt/ruby-enterprise/bin/:$PATH"
}
Then I had to add gemfile.lock and gemfile to the repository and the BAM!

the below solution works for capistrano 2. for version 3 and up use the capistrano-rbenv plugin.
assuming you're using the bash shell and have rbenv configured in something along the lines of a bashrc or profile file (globally in /etc or on a user-by-user basis) the problem is that capistrano does not use a so-called login shell which is required to have these files loaded (which, in the end, load rbenv).
for that purpose you might want to instruct capistrano to use such a shell:
default_run_options[:shell] = '/bin/bash --login'
put that into your deploy.rb. also has the benefit of keeping you DRY by not introducing another location to manage your rbenv $PATH additions -- in contrast to fatfrog's solution.

Answer 3

This happens because the bashrc rbenv init doesn't get executed. Move this to the top of your deployer user bashrc file and it will fix the problem:
if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
. /etc/bash_completion
fi
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

Answer 4

If your Issue is RVM on the server, then look at the help provided by rvm.io:
https://rvm.io/integration/capistrano/#gem

Answer 5

make sure you indeed have the rbenv installed in your server(sounds ridiculous, but it did happen in my case)
use this gem: https://github.com/yyuu/capistrano-rbenv

Answer 6

I was facing this problem and in my case the snippet from deploy/production.rb was as follows:
run "cd #{release_path} && bundle --without development test"
Had to install bundler as follows:
sudo apt-get install bundler
