红宝石：没有这样的文件加载 - ubygems（LoadError）运行冠橡胶时：create_staging [英] ruby: no such file to load -- ubygems (LoadError) when running cap rubber:create_staging

问题描述

我试图启动一个Amazon EC2实例如下 Railscast＃347的指令橡胶和Amazon EC2 。

I am trying to launch an Amazon EC2 instance following the instructions of Railscast #347 Rubber and Amazon EC2.

Rails项目的配置如下。该 .ruby版文件：

The Rails project is configured as follows. The .ruby-version file:

ruby-1.9.3

下面是的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'

我运行下面的橡胶命令：

$ rubber vulcanize complete_passenger_postgresql

除了其他文件的橡胶ruby.yml 产生如下（注释去掉）：

Besides other files the rubber-ruby.yml is generated as follows (comments removed):

# 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}"

与 nirvdrum 的在IRC聊天后，我已经修改 RUBY_VERSION：1.9.3 到 RUBY_VERSION：1.9.3 -p448 ，并给它一个尝试。同样的错误，虽然。

After chatting with nirvdrum on IRC I already change the ruby_version: 1.9.3 to ruby_version: 1.9.3-p448 and gave it a try. Same error though.

我粘在教程中，只配置了强制设置：

I sticked to the tutorial and only configured the mandatory settings:

# config/rubber/rubber.yml
app_name: ...
domain: ...
access_key: ...
secret_access_key: ...
account: ...
key_name: ...

继教程中，我测试设置运行：

Following the tutorial I test the setup running:

$ cap rubber:create_staging

该脚本的，而安装并重新启动实例，但同时它停止后运行：

The script runs for a while installing and restarting instances but after a while it stops:

检查一个Ruby安装的/ usr /本地/红宝石通过的 SSH 的服务器上显示，它有尚未安装

Checking for a Ruby installation in /usr/local/rubies via ssh on the server shows that it has not been installed.

这是张贴在Freenode的IRC的＃rubberec2 的作为我的问题评论：

This was posted in the freenode IRC #rubberec2 as a comment on my problem:

• 如何避免Ubygems加载错误

不过，我想不出如何应用这个到橡胶配置。

However, I cannot figure out how to apply this onto the Rubber configuration.

推荐答案

由于在这个问题说我产生了橡胶的配置文件，包括橡胶ruby.yml 。

As stated in the question I generated the configuration files for Rubber including rubber-ruby.yml.

# config/rubber/rubber-ruby.yml
...
ruby_build_version: 20130501
ruby_version: 1.9.3
...

我重复整个过程与橡胶相同版本（我只是固定的版本 2.5.2 ，因为有更新同时）。这一次，我注意到 RUBY_VERSION 设置为 1.9.3-P392 正如你所看到的此处。看来，如果我无意中修改这个设置？！

I repeated the whole process with the same version of Rubber (I just fixed the version to 2.5.2 since there is an update meanwhile). This time I noticed that the ruby_version is set to 1.9.3-p392 as you can see here. It seems as if I accidently modified this setting?!

复归这种变化在部署的实际工作作为预期。

Reverting this change the deployment actually works as expected.

如上所述，在此期间橡胶2.5.3出版含有更新设置 ：

As mentioned, in the meantime Rubber 2.5.3 was published which contains updated settings:

# config/rubber/rubber-ruby.yml
...
ruby_build_version: 20130628
ruby_version: 1.9.3-p448
...

我也尝试了新版本对于那些谁是好奇。它的工作原理也是如此。
非常感谢凯文·梅纳尔和马特·康韦谁坚持回答我的问题，在项目的IRC频道。

I also tried the new version for those who are curious. It works as well.
Big thanks to Kevin Menard and Matt Conway who persevered answering my questions in the IRC channel of the project.
