Rails 3.2.2 RVM系统广泛Capistrano安装无法找到宝石

Question

我真的非常迫切需要这个问题的帮助,而且还有点失落.

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,但它无法成功运行捆绑安装 - 部署.

cap staging deploy适用于现有的Ubuntu系统,但新服务器是一个常量失败,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会产生预期的结果

服务器上的rvm系统似乎是正确的

my-home$ rvm list

  rvm rubies

  # => - current
  # =* - current && default
  #  * - default

 my-home$ rvm info

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

但是应用程序目录中存在一个史诗般的失败,因为./vendor/bundle中没有任何内容

系统是Ubuntu 11.04,ruby使用rvm系统安装,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

另外两个升级和生产文件是....

部署/ staging.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/ production.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"  
 }

因此,失败是尝试将install --deployment捆绑在新交付的应用程序目录中.如果捆绑安装--nodeployment运行它工作正常!

我做错了什么或没有配置.我花了两天的时间试图解决这个问题,但似乎没有任何意义,因为为什么thios不会工作

Answer 1

你不得不错过capistrano的rvm说明:https://rvm.io/integration/capistrano/

只是阅读它们,我会建议你使用宝石版本,它基本上可以让你选择适当的红宝石:

安装:

gem install rvm-capistrano

或者添加到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.

但最好去检查文档,因为有更多选项:https://rvm.io/integration/capistrano/
