[英]Installing Rubber for proper Launch of instance creation
I am trying to launch an Amazon EC2 instance using Rubber. 我正在尝试使用Rubber启动Amazon EC2实例。
cap rubber:create_staging
rubber-ruby.yml reflects a version in use rubber-ruby.yml反映使用中的版本
ruby_build_version: 20141027
ruby_version: 1.9.3-p550
However upon cap rubber:create_staging
capistrano immediately aborts with 但是在使用cap rubber:create_staging
capistrano立即中止
LoadError: cannot load such file -- rubber
/Users/you/r/rubbertest/Capfile:14:in `require'
with the capfile stating capfile说明
$:.unshift "#{root}/vendor/plugins/rubber/lib/" # line 13
require 'rubber' # line 14
So I assumed a rubber gem would be necessary. 所以我认为橡胶宝石是必要的。 The gem file edited (without capistrano the process failed early) 修改了gem文件(没有capistrano,该过程会早期失败)
gem 'capistrano', '~> 3.1.0'
gem 'capistrano-bundler', '~> 1.1.2'
gem 'capistrano-rails', '~> 1.1.1'
gem 'capistrano-rvm'
gem 'rubber'
And the process went one step further to another failure: 整个过程又一步又走向了另一个失败:
NoMethodError: undefined method `instance' for Capistrano::Configuration:Class
/Users/you/.rvm/gems/ruby-1.9.3-p551/gems/rubber-1.15.0/lib/rubber/capistrano.rb:1:in `<top (required)>'
/Users/you/r/rubbertest/Capfile:17:in `require'
the capistrano.rb file is a one liner capistrano.rb文件是一个内衬
Capistrano::Configuration.instance.load(File.join(File.dirname(__FILE__), 'recipes', 'rubber.rb'))
being called by the capfile 被capfile调用
Rubber::initialize(root, env)
require 'rubber/capistrano' # line 17
Another oddity is that the final instruction of the Capfile calls 另一个奇怪的是,Capfile的最终指令调用
Dir['vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }
and that directory is empty which is consistent with the instructions : Rubber can be installed as a rubygem (recommended) 并且该目录为空,这与说明一致: 可以将橡胶安装为rubygem(推荐)
I have run this twice with identical behaviour. 我已经以相同的方式运行了两次。
However these gaps (no reference to rubber gem, nor capistrano, calling vendor/plugins against gemmification preference) tell me that some step is missing here. 但是,这些差距(既没有提及橡胶宝石,也没有capistrano,没有针对宝石化偏好调用供应商/插件)告诉我,这里缺少一些步骤。 where has this gone wrong? 这出了什么问题?
It appears that gem identity matters : 宝石身份似乎很重要:
# gem 'rubber'
would only install version 1.15.0, By specifying 只能安装1.15.0版,方法是指定
gem 'rubber', '3.1.0'
then cap rubber:config
runs. 然后cap rubber:config
运行。 create_staging will start running as well. create_staging也将开始运行。
note the version is an issue: the one originally posted was somehow requiring a separate capistrano entry and leading to a later failure. 请注意,该版本是一个问题:最初发布的版本以某种方式需要单独的capistrano条目,并导致以后的失败。 The list of versions is here 版本列表在这里
