“bash: bundle: command not found” - cap 中止

Question

这是我的deployment.rb文件。

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

set :stage, 'production'
set :application, "gobgob-ror"
set :repo_url, 'git@github.com:narhamah/gobgob-ror.git'
# Default branch is :master
# ask :branch, `git rev-parse --abbrev-ref HEAD`.chomp

# Default deploy_to directory is /var/www/my_app_name
set :deploy_to, '/home/ubuntu/gobgob-ror'

# Default value for :scm is :git
set :scm, :git
set :branch, "master"

#set :user, "ubuntu"
set :use_sudo, false
set :rails_env, "production"
set :deploy_via, :remote_cache
set :ssh_options, { user: 'ubuntu', :forward_agent => true, :port => 22, keys: ["#{ENV['HOME']}/.ssh/id_rsa"]}


# Default value for :format is :pretty

# Default value for :log_level is :debug
# set :log_level, :debug

# Default value for :pty is false
set :pty, true
server "xx.xx.xxx.xxx", roles: [:app, :web, :db], :primary => true

set :normalize_asset_timestamps, %{public/images public/javascripts public/stylesheets}
# Default value for :linked_files is []
set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml')

# Default value for linked_dirs is []
set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system')

# Default value for default_env is {}
# set :default_env, { path: "/opt/ruby/bin:$PATH" }

# Default value for keep_releases is 5
set :keep_releases, 5

namespace :deploy do
  desc "Start the application"
  task :start do
    on roles(:app) do
      execute "cd #{current_path} && RAILS_ENV=#{fetch(:stage)} bundle exec puma -b 'unix://#{shared_path}/sockets/puma.sock' -S #{shared_path}/sockets/puma.state --control 'unix://#{shared_path}/sockets/pumactl.sock' >> #{shared_path}/log/puma-#{fetch(:stage)}.log 2>&1 &", :pty => false
    end
  end

  desc "Stop the application"
  task :stop do
    on roles => :app  do
      execute "cd #{current_path} && RAILS_ENV=#{fetch(:stage)} bundle exec pumactl -S #{shared_path}/pids/puma.state stop"
    end
  end

  desc "Restart the application"
  task :restart do
    on roles(:app) do
      execute "cd #{current_path} && RAILS_ENV=#{fetch(:stage)} bundle exec pumactl -S #{shared_path}/pids/puma.state restart"
    end
  end

  desc "Status of the application"
  task :status do 
    on roles(:app) do
      execute "cd #{current_path} && RAILS_ENV=#{fetch(:stage)} bundle exec pumactl -S #{shared_path}/pids/puma.state stats"
    end
  end
end

after "deploy", "deploy:restart"
after "deploy", "deploy:cleanup"

现在我做了bundle exec cap production deploy 。 在巨大的日志之后，我得到了以下错误。

Answer 1

看起来您的服务器上没有安装bundler gem。 它应该被安装并且bundle可执行文件应该在$PATH可用。

尝试直接在服务器上执行bundle --version以确定实际上缺少bundler 。

如果是这种情况，请安装bundler gem，您应该很高兴。 或者要真正保持自动化，您可以定义一个 capistrano 任务来检查bundle可执行文件是否可用，如果不可用则安装bundler gem。 您可以在bundler:install任务之前执行此任务。

更新：如果您正在使用一些 ruby​​ 管理器，如rvm或chruby或类似的东西， bundle可执行文件可能无法用于您的 Capistrano 部署任务。 在这种情况下，您必须确保部署任务获得登录 shell，以便执行所有这些 shell 脚本。

这是我现在解决问题的方法。 我得到了Rustam A. Gasanov 的帮助以使其正常工作。 非常感谢！！
