ruby：没有这样的文件加载 – 运行cap rubber时的ubygems（LoadError）：create_staging
我正在尝试按照Railscast＃347 Rubber和Amazon EC2的指示启动Amazon EC2实例。
Rails项目配置如下。 .ruby-version文件：
ruby-1.9.3
这是Gemfile ：
source 'http://rubygems.org' ruby '1.9.3' gem 'rails', '~> 3.2.13' gem 'rb-readline', '~> 0.5.0' gem 'counter_culture', '~> 0.1.12' gem 'jquery-rails', '~> 3.0.2' gem 'therubyracer', '~> 0.11.4', require: 'v8' gem 'attribute_normalizer', '~> 1.1.0' group :assets do gem 'sass-rails', '~> 3.2.5' gem 'coffee-rails', '~> 3.2.2' gem 'uglifier', '~> 2.1.1' end group :development do gem 'debugger', '~> 1.6.0' end group :development, :test do gem 'sqlite3', '~> 1.3.7' end group :production do gem 'pg', '~> 0.15.1' end gem 'rubber', '~> 2.5.2' gem 'open4' gem 'gelf' gem 'graylog2_exceptions', :git => 'git://github.com/wr0ngway/graylog2_exceptions.git' gem 'graylog2-resque'
我运行以下橡胶命令：
$ rubber vulcanize complete_passenger_postgresql
除了其他文件， rubber-ruby.yml生成如下（注释已删除）：
# config/rubber/rubber-ruby.yml packages: [build-essential, git-core, subversion, curl, autoconf, bison, ruby, zlib1g-dev, libssl-dev, libreadline6-dev, libxml2-dev, libyaml-dev] ruby_build_version: 20130501 ruby_version: 1.9.3 ruby_path: "/usr/local/rubies/#{ruby_version}"
在IRC上与nirvdrum聊天后，我已经将ruby_version: 1.9.3更改为ruby_version: 1.9.3-p448并尝试了一下。 但是同样的错误。
我坚持使用教程，只配置了强制设置：
# config/rubber/rubber.yml app_name: ... domain: ... access_key: ... secret_access_key: ... account: ... key_name: ...
按照教程我测试运行的设置：
$ cap rubber:create_staging
该脚本运行一段时间安装并重新启动实例，但一段时间后它会停止：

通过服务器上的ssh检查/usr/local/rubies的Ruby安装表明它尚未安装 。
这是作为对我的问题的评论发布在freenode IRC ＃rubberec2 ：
- 如何避免Ubygems加载错误
但是，我无法弄清楚如何将其应用到Rubber配置中。
如问题中所述，我生成了Rubber的配置文件，包括rubber-ruby.yml 。
# config/rubber/rubber-ruby.yml ... ruby_build_version: 20130501 ruby_version: 1.9.3 ...
我用相同版本的Rubber重复整个过程（我只是将版本修复为2.5.2因为同时有更新）。 这次我注意到ruby_version设置为1.9.3-p392 ruby_version ，你可以在这里看到。 似乎我意外地修改了这个设置 ？！
恢复此更改， 部署实际上按预期工作。
如上所述，同时发布了包含更新设置的 Rubber 2.5.3：
# config/rubber/rubber-ruby.yml ... ruby_build_version: 20130628 ruby_version: 1.9.3-p448 ...
我也为那些好奇的人尝试了新版本。 它也有效。
非常感谢Kevin Menard和Matt Conway坚持在项目的IRC频道回答我的问题。
