Capistrano部署中“未安装宝石捆绑器”

Question

Here is the error caused by rake in Capistrano deployment. The error also causes the rollback and failure of the rails 3.1.3 deployment (with rvm installed for single user).

 ** [out :: 76.195.225.93] ←[31mERROR: Gem bundler is not installed, run `gem in
    command finished in 54ms
*** [deploy:update_code] rolling back
  * executing "rm -rf /var/www/byop/releases/20120302230229; true"

gem list shows bundler 1.0.22 installed. What could cause the error? Is it because of the rvm? Thanks so much.

Answer 1

The error disappeared after adding the following in deploy.rb and deployed successfully:

   task :gems, :roles => :web, :except => { :no_release => true } do 
     run "cd #{current_path}; #{shared_path}/bin/bundle unlock" 
     run "cd #{current_path}; nice -19 #{shared_path}/bin/bundle install vendor/" # nice -19 is very important otherwise DH will kill the process! 
     run "cd #{current_path}; #{shared_path}/bin/bundle lock" 
   end
