在这个问题上，我真的非常需要帮助，而且有点失落。

我正在尝试使用 Capistrano Ext 部署新的生产服务器以允许登台和生产服务器，但它无法成功运行 bundle install --deployment。

cap staging deploy 在现有的 Ubuntu 系统上运行良好，但新服务器经常失败，如下所示

my-app$ sh -c 'cd /var/www/html/rails/myapp/releases/20120519174459&& export PATH=/usr/local/bin:/usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/opt/local/bin:/usr/local/rvm/gems/ruby-1.9.3-p194/bin:/usr/local/rvm/gems/ruby-1.9.3-p194@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p194/bin:/usr/local/rvm/bin && bundle install --deployment'

在任何其他目录中， ruby​​ -v 和 rails -v 都会产生预期的结果

服务器上的 rvm 系统范围似乎是正确的

  # =* - current && default

  RVM is not a function, selecting rubies with 'rvm use ...' will not work.
  You need to change your terminal settings to allow shell login.

系统是 Ubuntu 11.04，ruby 使用 rvm 系统范围安装，默认为 1.93

deploy.rb 如下：

# This has been added due to multi deployment staging
set :stages, %w(staging production)
set :default_stage, "staging"

require 'capistrano/ext/multistage'

default_run_options[:pty] = true 

set :user, 'appuser'
set :application, "app"
set :keep_releases, 10

set :deploy_to, "/var/www/html/rails/#{application}"
set :repository,  "appuser@gitserver:/myapps/rails/#{application}.git"
set :deploy_via, :copy
set :ssh_options, {:forward_agent => true}
set :scm, :git 
set :branch, 'master'
set :scm_verbose, true
set :use_sudo, false

# This has been added due to multi deployment staging
# since :domain is defined in another file (staging.rb and production.rb),
# we need to delay its assignment until they're loaded
set(:domain) { "#{domain}" }
role(:web) { domain }
role(:app) { domain }
role(:db, :primary => true) { domain }

# If you are using Passenger mod_rails uncomment this:
namespace :deploy do
  desc "cause Passenger to initiate a restart"
  task :restart do
    run "touch #{current_path}/tmp/restart.txt"
  end
  desc "reload the database with seed data"
  task :seed do
    run "cd #{current_path}; rake db:seed RAILS_ENV=production"
  end
end

before "deploy:assets:precompile", :bundle_install

after "deploy:update_code", :bundle_install
desc "install the necessary prerequisites"
task :bundle_install, :roles => :app do
  run "cd #{release_path}&& export PATH=/usr/local/bin:/usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/opt/local/bin:/usr/local/rvm/gems/ruby-1.9.3-p194/bin:/usr/local/rvm/gems/ruby-1.9.3-p194@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p194/bin:/usr/local/rvm/bin && bundle install --deployment"
  run "cp -Rf #{shared_path}/config/* #{release_path}/config/"
end

其他两个暂存和生产文件是....

部署/登台.rb

set :domain, "staging.myapp.com"
set :rails_env, "staging"
set :default_environment, {  
   'PATH' => "/usr/local/bin:/usr/local/mysql/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/opt/local/bin"  
}

部署/生产.rb

set :domain, "production.myapp.com"
set :rails_env, "production"
set :default_environment, {  
  'PATH' => "/usr/local/rvm/gems/ruby-1.9.3-p194/bin:/usr/local/rvm/gems/ruby-1.9.3-p194@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p194/bin:/usr/local/rvm/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/mysql/bin"  
 }

所以失败是试图将 install --deployment 捆绑在新交付的应用程序目录中。如果 bundle install --nodeployment 运行它工作正常！

我做错了什么或没有配置。我花了 2 天时间试图解决这个问题，但为什么 thios 不起作用似乎没有任何意义

您必须错过 capistrano 的 rvm 说明：https ://rvm.io/integration/capistrano/

只需阅读它们，我会建议您使用 gem 版本，它基本上可以让您选择合适的 ruby​​：

安装：

gem install rvm-capistrano

或添加到 Gemfile：

gem 'rvm-capistrano'

示例 Capfile deploy.rb ：

set :rvm_type, :system    # :user is the default
set :rvm_ruby_string, ENV['GEM_HOME'].gsub(/.*\//,"") # Read from local system

require "rvm/capistrano"  # Load RVM's capistrano plugin.

但最好去查看文档，因为有更多选项可用：https ://rvm.io/integration/capistrano/

  1. 不要使用 rvm1/capistrano3 或 rvm/capistrano；不要设置：pty。

  2. 将服务器上的 runner 用户更改~/.rvmrc为 - 请注意，它必须位于它在不以交互方式运行时杀死自己的行之前：

# get rvm for non-interactive shells (eg capistrano) too
source /etc/profile.d/rvm.sh
export BASH_ENV=$HOME/.bashrc
export rvm_is_not_a_shell_function=0

# If not running interactively, don't do anything
[ -z "$PS1" ] && return
