无法使用Capistrano和RVM部署Rails应用程序

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

当我跑cap deploy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。

以下是staging.example.com上rvm info的输出:

ruby-1.9.2-p180:

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

答案 1 :(得分:2)

failed: "rvm_path=$HOME/.rvm/ /usr/local/bin/rvm-shell '1.9.2' -c 'bundle install --gemfile /home/example/staging.example.com/releases/20110714180125/Gemfile --path /home/example/staging.example.com/shared/bundle --deployment --quiet --without development production'

确保在服务器中运行bundle install时安装了捆绑程序并使用了正确的路径。如果未安装,请运行gem install bundler进行安装。

答案 2 :(得分:1)

如果您安装了bundler,请执行以下操作:

更改此行 - > set :rvm_ruby_string, '1.9.2'

到此 - > set :rvm_ruby_string, 'ruby-1.9.2-p180'

这适合我。
