Capistrano 3 deployment broke for some reason

Question

Okay,

I'm running into some weird issue with our deployment no longer working anymore. I cannot track everything that changed, but I'm hoping someone can help me out with debugging this issue and find out what is going wrong.

deploy.rb

# config valid only for current version of Capistrano    
lock '3.4.0'

set :application, 'app_name'
set :repo_url, 'github_url'
set :deploy_to, '/home/user/path'

# Source Control Configuration
set :scm, :git
# Produces: Please enter the name of the branch. (develop):
set(:branch, ask('the name of the branch.', 'develop'))

# Ask whether we want to perform a backup.
# Produces: Please enter whether to perform a backup of the database? (Y):
set(:backup, ask('whether to perform a backup of the database?', 'Y'))

puts("setting branch to: #{fetch(:branch)}")

set :user, 'my_user'

set :assets_roles, [:web, :app, :vm]
set :keep_assets, 2

set :linked_files, fetch(:linked_files, []).push('.chamber.pem', 'Procfile', '.env')
set :linked_dirs, fetch(:linked_dirs, []).push('data', 'tmp', 'log', 'uploads')

set :keep_releases, 10

set :bundle_path, nil
set :bundle_binstubs, nil
set :bundle_flags, '--system'

set :rvm1_map_bins, fetch(:rvm1_map_bins, []).push('honeybadger')

# Slack integration options
set :slack_via_slackbot, Settings.slack.via_slackbot
set :slack_team, Settings.slack.team
set :slack_token, Settings.slack.token
set :slack_icon_emoji, -> { Settings.slack.icon_emoji }
set :slack_channel, -> { Settings.slack.channel }
set :slack_username, -> { Settings.slack.username }
set :slack_run_starting, -> { Settings.slack.run_starting }
set :slack_run_finished, -> { Settings.slack.run_finished }
set :slack_run_failed, -> { Settings.slack.run_failed }
set :slack_msg_finished, -> { "@channel #{ENV['USER'] || ENV['USERNAME']} has deployed branch *#{fetch :branch}* of #{fetch :application} to *#{fetch :rails_env}*." }
set :slack_msg_failed, -> { "#{ENV['USER'] || ENV['USERNAME']} failed to deploy branch #{fetch :branch} of #{fetch :application} to #{fetch :rails_env, 'production'}." }

# Rake config
SSHKit.config.command_map[:rake] = 'bundle exec rake'

before 'deploy:started', 'deploy:rm:stop'
after 'deploy:rm:stop', 'deploy:rm:backup'
after 'deploy:finished', 'deploy:rm:start'
after 'deploy:migrate', 'deploy:rm:seed

Capfile

# Load DSL and set up stages
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
require 'rvm1/capistrano3'  # Do not use capistrano/bundler
require 'whenever/capistrano'
require 'capistrano/honeybadger'
require 'slackistrano/capistrano'

# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

require 'net/ssh/proxy/command'
def vm(tunnel:, tunnel_user: fetch(:user), vm_user: fetch(:user))
  server "#{fetch(:stage)}-vm01", {
    roles: [:vm],
    # The user on the VM
    user: vm_user,
    ssh_options: {
      # The user on the machine we're tunneling through
      proxy: Net::SSH::Proxy::Command.new("ssh #{tunnel_user}@#{tunnel} -W %h:%p"),
    }
  }
end

So I can run the cap command locally, and it does part of the work. Had some issues first with the new sprockets, but now it's complaining about the following when it needs to precompile the assets:

Answer 1

As your error message saying bash: bundle: command not found

It seems you dont have the gem bundler installed on the server

install bundler gem on server by running the following command that should do the trick

gem install bundler
