Ruby on rails capistrano和chruby在错误的ruby中寻找bundler

我正在尝试在chruby管理的新服务器和ruby版本上部署Capistrano3

工作规范中规定的所有测试均正常

当我尝试进行部署时，它似乎在尝试在系统ruby中查找bundler，而不是在deploy.rb中指定的chruby版本

set :chruby_ruby, 'ruby-2.1.2'

我已经在服务器上安装了ruby 2.1.2和ruby install，如果我以部署用户的身份登录，就会发现使用的是正确的ruby

deploy@server:~$ ruby -v
ruby 2.1.2p95 (2014-05-08 revision 45877) [i686-linux]

部署中的错误是

更新

在2.1.2环境中的服务器上执行gem安装捆绑程序似乎可以让它正常工作，但我仍然在输出中收到以下令人不安的消息
