我有一个我用Capistrano部署的Rails应用程序.我在服务器上安装了RVM,因为我想使用更新版本的
Ruby并将其添加到我的deploy.rb文件中(根据我发现的各种说明)：
$:.unshift(File.expand_path('./lib',ENV['rvm_path']))
require 'rvm/capistrano'
set :rvm_ruby_string,'1.9.2'
set :rvm_type,:user
当我运行cap cap时,会发生这种情况：
[staging.example.com] executing command
** [out :: staging.example.com] /usr/local/lib/site_ruby/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem bundler (>= 0) (

为什么capistrano使用Ruby 1.8？我的道路显然也搞砸了.
这是staging.example.com上rvm info的输出：

解决方法
实际上rvm-capistrano文档页面上的最新文档声明它必须是这样的：
# RVM bootstrap: change to your Ruby and GemSet require 'rvm/capistrano' set :rvm_ruby_string,ENV['GEM_HOME'].gsub(/.*\//,"") set :rvm_type,:user
