PObundler/capistrano is not installing gems with correct ruby version
text
Body
copied!<p>I'm trying to deploy my first app on a server with Capistrano, and I'm a bit <strong>lost with managing gemsets and ruby version</strong>.</p> <p>These are my (server and workstation) versions :</p> <ul> <li>Rails 3.2.8</li> <li>RVM 1.16.17</li> <li>Gem 1.8.24</li> <li>Bundler 1.2.1</li> <li>pg gem 0.14.1</li> </ul> <p>My gemset are :</p> <p>Gemsets for ruby-1.9.3-p194 (found in /usr/local/rvm/gems/ruby-1.9.3-p194)</p> <ul> <li>(default)</li> <li>global</li> <li>=> rail3dev20120606</li> </ul> <p>I set the default gemset with :</p> <pre><code>rvm use 1.9.3-p194@rail3dev20120606 --default --passenger </code></pre> <p>When I run a :</p> <pre><code>cap bundle:install </code></pre> <p>The task end with success, but when I do a :</p> <pre><code>gem list </code></pre> <p>There are many <strong>missing gems</strong> though they are present in my Gemfile. When I go to check my gems in <strong>/var/www/opf/shared/bundle/ruby/</strong> I find a folder called <strong>1.9.1</strong> and in /var/www/opf/shared/bundle/ruby/1.9.1/gems/ I can fond all of my needed gems (specified in Gemfile). I'm sure there is a problem with ruby version, but how do I solve this ?</p> <p>At the moment, if I do any rake command, I got a ruby crash [Bug] Segmentation fault, as it try to access the db and using postgresql_adapter :</p> <pre><code>/var/www/opf/shared/bundle/ruby/1.9.1/gems/activerecord-3.2.8/lib/active_record/connection_adapters/postgresql_adapter.rb:1213: [BUG] Segmentation fault </code></pre> <p>I think as many gems are missing there must have some gem dependencies not verified, and maybe a gem is using an incompatible ruby version 1.9.1 though it expect a 1.9.3.</p> <p>I think the issue is around managing ruby versions and gems. I'm certainly doing some mix with gemset and my capistrano deployement.</p> <p>I'm missing experience and info. Could anybody advise me how to handle this on the server ? What are the best practices ?</p> <p><strong>How am I suppose to update my ruby version ? with Capistrano deploy.rb ? manually ? with/without rvm ? I saw a new version of ruby 1.9.3-p327 has just released.</strong></p> <p><strong>Should I use gemset or not ? What about the :rvm_ruby_string in my deploy.rb. Is it correctly spelled or should I remove the p194 part ? Should I Remove the :rvm_ruby_string ? Keep it ? Use a .rvmrc file ???</strong></p> <p><strong>I'm really lost and some kind help would be welcome.</strong></p> <p>This is my config/deploy.rb in any case :</p> <pre><code>require 'bundler/capistrano' require File.join(File.dirname(__FILE__), 'deploy') + '/capistrano_database' set :rvm_type, :system set :rvm_ruby_string, 'ruby-1.9.3-p194@rail3dev20120606' require 'rvm/capistrano' set :application, 'opf' set :deploy_to, '/var/www/opf' set :rails_env, 'production' set :user, 'the_user' set :use_sudo, false set :group_writable, false set :scm, :git set :repository, 'git@github.com:user/opf.git' set :branch, 'master' default_run_options[:pty] = true set :deploy_via, :remote_cache server '192.168.5.200', :web, :app, :db, :primary => true # If you are using Passenger mod_rails uncomment this: namespace :deploy do task :start do ; end task :stop do ; end task :restart, :roles => :app, :except => { :no_release => true } do run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}" end end </code></pre> <p>Thanks for any help</p>
