在生產Rails應用程序中，即使指示bundler跳過開發組，也會收到Bundler :: GemNotFound錯誤

Question

在我的生產服務器上，我不想包含gem rspec rails。但是，試圖啓動我的導軌的服務器時，我得到一個錯誤：

/home/deployer/.rvm/gems/ruby-1.9.3-p392/gems/bundler-1.3.2/lib/bundler/spec_set.rb:92:in `block in materialize': Could not find rspec-rails-2.12.0 in any of the sources (Bundler::GemNotFound) 
    from /home/deployer/.rvm/gems/ruby-1.9.3-p392/gems/bundler-1.3.2/lib/bundler/spec_set.rb:85:in `map!' 
    from /home/deployer/.rvm/gems/ruby-1.9.3-p392/gems/bundler-1.3.2/lib/bundler/spec_set.rb:85:in `materialize'

    from /home/deployer/.rvm/gems/ruby-1.9.3-p392/gems/bundler-1.3.2/lib/bundler/definition.rb:159:in `specs_for' 
    from /home/deployer/.rvm/gems/ruby-1.9.3-p392/gems/bundler-1.3.2/lib/bundler/runtime.rb:13:in `setup' 
    from /home/deployer/.rvm/gems/ruby-1.9.3-p392/gems/bundler-1.3.2/lib/bundler.rb:127:in `setup' 
    from /var/www/myapp/releases/20130311164742/config/boot.rb:8:in `<top (required)>'

    from /home/deployer/.rvm/rubies/ruby-1.9.3-p392/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' 
    from script/rails:5:in `<main>' 

我的Gemfile看起來像：

source 'http://rubygems.org' 
ruby "1.9.3" 

gem 'rails', '3.2.11' 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
end 

gem 'haml', '3.1.7' 
gem 'devise', '2.2.0' 
gem 'koala', '1.6.0' 
gem "mongoid", "~> 3.0.0" 
gem "braintree", "~>2.22.0" 


group :development, :test do 
    gem 'rspec-rails', '2.12.0' 
end 

在我的配置/的boot.rb文件，我告訴打捆只尋找默認或相關環境包括寶石：

require 'rubygems' 

# Set up gems listed in the Gemfile. 
ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__) 

if File.exists?(ENV['BUNDLE_GEMFILE']) 
    require 'bundler' 
    Bundler.setup(:default, ENV["RAILS_ENV"]) 
end 

我驗證過RAILS_ENV環境變量設置爲生產，通過運行：

$ echo $RAILS_ENV 

並獲得'生產'回來。

爲什麼它仍然在尋找那個寶石，即使我告訴它不設置它？

這是一個錯字嗎？ echo $RAILS_ENV。你錯過了Rails中的's'。
