Ruby on rails Bundler在部署期间未正确安装gems（我认为是RVM问题）

我在一个盒子上运行了一个应用程序，我正在尝试向盒子中添加另一个应用程序

它们都使用RVM

问题是，对于我添加到框中的新应用程序，我的部署过程失败

部署时，我会调用

RVM info 

看看我用的是什么ruby。以下是输出：

引发此错误：

我在这里束手无策：看起来我在使用ruby1.9.3-p392，但bundler告诉我需要ruby>=1.9.3

这是我的.bundle/config：

---
BUNDLE_PATH: vendor/bundle
BUNDLE_DISABLE_SHARED_GEMS: '1'
BUNDLE_FROZEN: '1'

另外，如果我ssh到该框中，看起来我使用的是正确的ruby：

$ which ruby
/usr/local/rvm/rubies/ruby-1.9.3-p392/bin/ruby

运行bundle安装可以很好地工作

有什么想法吗

编辑#1

我正在使用Vlad，这里是deploy.rb：

set :repository,  repo_location
set :revisions,   5
set :revision, "HEAD"
set :domain, domain
set :user,        login_user
set :deploy_to,   deploy_dir
set :deploy_env, "production"

namespace :vlad do

  desc 'Restart Passenger'
  remote_task :restart_app do
    puts "Restarting passenger..."
    run "touch #{current_release}/tmp/restart.txt"
  end

  desc 'Runs our full deployment'
    task :deploy => ['vlad:update', 
                     'vlad:symlink', 
                     'vlad:rvm_info',
                     'vlad:update_bundle',
                     'vlad:migrate_database',
                     'vlad:cleanup', 
                     'vlad:restart_app']

  desc 'Symlinks your custom directories'
  remote_task :symlink do
    run "ln -s #{shared_path}/environments #{latest_release}/config/environments"
    run "ln -s #{shared_path}/database.yml #{current_path}/config/database.yml"
    run "ln -s #{shared_path}/config.yml #{current_path}/config/config.yml"
  end

  desc 'Show RVM Info for debug purposes'
  remote_task :rvm_info do
    run "cd #{current_path} && rvm info" 
  end

  desc 'Update the Bundler bundle we use to include any new gems in the Gemfile'
  remote_task :update_bundle do
    run "cd #{current_path} && bundle install --deployment" 
  end

  # copied from the vlad source, integrate migrate does not work as it's missing
  # the && between the cd and the db migrate task itself. bug is already tracked
  # at http://rubyforge.org/tracker/?group_id=4213&atid=16258&func=detail&aid=28445, 
  # but currently does not do anything.
  remote_task :migrate, :roles => :app do
    break unless target_host == Rake::RemoteTask.hosts_for(:app).first

    directory = case migrate_target.to_sym
                when :current then current_path
                when :latest  then latest_release
                else raise(ArgumentError, "unknown migration target #{migrate_target.inspect}")
                end

    run(["cd #{directory}", 
         "bundle exec #{rake_cmd} db:migrate #{migrate_args} RAILS_ENV=#{rails_env}"].join(" && "))
  end

end

这不是rvm故障。。。这是关于如何运行命令的问题，

vlad

不像使用

ssh

那样使用登录会话，因此需要手动加载rvm：

set :command_prefix, [". `/usr/local/rvm/bin/rvm . do rvm env --path`"]

---

我无法基于vlad代码对其进行测试，但这应该是一个良好的开端。

您使用的是capistrano吗？如果是，则显示capfileI正在使用Vlad-使用deploy.rb更新问题。

set :command_prefix, [". `/usr/local/rvm/bin/rvm . do rvm env --path`"]
