我正在尝试在由 chruby 管理的新服务器和 ruby​​ 版本上使用 capistrano 3 进行部署。

capistrano 文档中指定的所有测试都可以正常工作。

当我尝试进行部署时，它似乎试图在系统 ruby​​ 中找到捆绑程序，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带有 ruby​​-install 的 ruby​​ 2.1.2，如果我以部署用户身份登录，它似乎正在使用正确的 ruby

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

部署的错误是

deploy.rb (下面的都是默认的)

lock '3.2.1'

set :application, 'oentry'
set :repo_url, 'git@1nnn.nnn.nnn.nnn:/opt/git/oentry.git'
set :chruby_ruby, 'ruby-2.1.2'

production.rb（下面的都是默认的）

role :app, %w{deploy@nnn.nn.nnn.nnn}
role :web, %w{deploy@nnn.nn.nnn.nnn}
role :db,  %w{deploy@nnn.nn.nnn.nnn}

更新。

在 2.1.2 环境中的服务器上执行 gem install bundler 似乎可以使它工作，但我仍然在输出中收到以下令人不安的消息

DEBUG[1b6631e7]     chruby: unknown Ruby: ruby-1.9.3-p392
