我想部署sinatra项目。
运行命令cap production deploy。
错误：
cap aborted!
LoadError: cannot load such file -- rvm/capistrano

设置capistrano Capgile文件
# Load DSL and set up stages
require 'capistrano/setup'
# Include default deployment tasks
require 'capistrano/deploy'
# If you are using rvm add these lines:
require 'capistrano/rvm'
set :rvm_type, :user
set :rvm_ruby_version, '2.3.1-p112'
#Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }
在部署文件中，我为rvm
添加了以下内容#config/deploy.rb
#RVM and bundler settings
set :bundle_cmd, "/home/deploy/.rvm/gems/ruby-2.3.1-p112@global/bin/bundle"
set :bundle_dir, "/home/deploy/.rvm/gems/ruby-2.3.1-p112/gems"
set :rvm_ruby_string, :local
set :rack_env, :production
我不明白为什么这个错误，也许是因为第一次在本地我使用rbenv来安装ruby和bundle install gems。但是在安装了rvm之后，在目录项目中使用命令rvm use 2.3.1.
ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]
如何解决这个问题？谢谢你提前。
