嗨，我想我遗漏了一些基本的东西。
我使用Capistrano部署到"集成"，然后部署到"测试"。
我似乎无法添加一个gem，然后用Capistrano成功部署到其中一个网站（"测试"）。然而，我可以成功地将其部署到另一个（"集成"）。
我正在尝试添加bootstrap sass'~>3.0.2'，但当我尝试添加它们时，其他gem也会出现同样的错误。
当我试图用"cap-testing-deploy"部署到"testing"时，我得到一个错误，读取
whenever --update-crontab registration --set environment=testing --roles db"
servers: ["test.calm.dhamma.org"]

etc..
我花了很长时间寻找答案，但没有成功。我确实有
require 'bundler/capistrano'
在我的Capfile.rb中，如下所示。
require "rvm/capistrano"
#set :rvm_type, :system # :user is the default
set :rvm_ruby_string, ENV['GEM_HOME'].gsub(/.*//,"") # Read from local system

after 'deploy:setup', :create_configs
desc 'Create the shared/config dir for various config files'
task :create_configs do
run "mkdir -p #{shared_path}/config"
run "touch #{shared_path}/config/database.yml"
end

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
我尝试过直接在"测试"网站中安装gem，方法是编辑那里的Gemfile和Gemfile.lock，使其与我的开发和"集成"网站上的一致，并运行捆绑包安装。
然后当我"捆绑显示"时，我得到
bundle show bootstrap-sass
....../.rvm/gems/ruby-1.9.3-p448/gems/bootstrap-sass-3.0.2.1
然后：
bundle exec gem list
Could not find bootstrap-sass-3.0.2.1 in any of the sources
Run `bundle install` to install missing gems.
帽子测试部署仍然失败
在工作的网站上，gem安装如下：
bundle show bootstrap-sass
...../registration/shared/bundle/ruby/1.9.1/gems/bootstrap-sass-3.0.2.1
这与我在不工作的网站上手动安装它的地方不同。
所以，我的问题是：
为什么Capistrano没有在一个网站上添加新的宝石，但在另一个网站却成功了？
我应该直接在我尝试过的不起作用的网站上安装gem吗？如果这是个好主意，我该如何将其安装在正确的位置？

现在让我的评论成为一个答案：
它现在正在工作——不同的ruby版本似乎存在问题。我在本地的测试中有1.9.7 p448，测试中有1.9.7 p484。我们只是将每台机器上的所有版本都设置为相同的版本，现在我可以使用Capistrano根据Gemfile的更改来更新gem。
