在生产rails应用程序中，得到Bundler::GemNotFound错误，即使指示Bundler跳过开发组

Question

在我的生产服务器上，我不想包含gem rspec rails。但是，当尝试使用rails s启动服务器时，我得到一个错误:

/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 script/rails:5:in `<main>'

我的gemfile看起来像:

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/启动。我告诉打包器只查找默认包含的gem或相关环境的gem:

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

我已经验证了RAILS_ENV环境变量被设置为生产，通过运行:

$ echo $RAILS_ENV

让"生产"回归。

为什么我告诉它不要设置，它还在寻找那颗宝石?

是不是打错了?echo $RAILS_ENV。你漏掉了Rails中的's'
