Capistrano的部署找不到某些宝石

Question

我一直在试图部署到使用Capistrano的车辆定位系统，和下面的命令扔了我很多的错误：

* executing "cd -- /home/work/for_linode/releases/20130317174830 && rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile && cp -- /home/work/for_linode/shared/assets/manifest.yml /home/work/for_linode/releases/20130317174830/assets_manifest.yml" 

这将导致以下：

我绝不使用Capistrano的手段方面的专家，而类似的问题在这里，都涉及到这是一个有点不同的问题，

你们可以帮忙弄清楚发生了什么事吗？

require "rvm/capistrano" 
load 'deploy/assets'

使用这段代码资产：

set :rvm_ruby_string, ENV['GEM_HOME'].gsub(/.*\//,"") 
set :bundle_without, [:development] 
require "rvm/capistrano" 
require "bundler/capistrano" 
load 'deploy/assets'
