我刚刚收购了Media Temple（dv）4.0服务器来部署我通过git存储库创建的Rails应用程序。我是Rails的新手，但Capistrano的部署看起来非常简单。尽管如此，我整天都在努力完成我的第一个Rails项目的部署。这是我在设置并检查后执行“cap production deploy -v”时遇到的错误：
** [out :: 64.207.184.51] rake aborted!
** [out :: 64.207.184.51] no such file to load -- rubygems
我一直在服务器上安装宝石，所以我不认为没有安装rubygems。这是经过几个小时的调试，为什么它告诉我我的公钥无效。
以下是我的配置文件：
Capfile：
require 'capistrano/ext/multistage'
load 'deploy'
load 'deploy/assets'
load 'config/deploy'
set :application, 'snippet'
set :domain, '[server IP address]'
set :user, 'root'
配置/ deploy.rb
require 'capistrano/ext/multistage'
default_run_options[:pty] = true
set :stages, ["production"]
set :default_stage, "production"
set :application, "[app name]"
set :scm, :git
set :repository, "git@github.com:[github.com repository]"
set :branch, "master"
set :user, "root"
set :use_sudo, false
set :deploy_via, :remote_cache
set :scm_passphrase, "[public ssh key passphrase]"
配置/部署/ production.rb
server "[server IP]", :app, :web, :db, :primary => true
set :deploy_to, "/var/www/vhosts/[domain]/httpdocs"
输出错误：

请帮忙！我在服务器上安装了RVM，Ruby，Passenger和Rails。
