RailsBridge“捆绑安装--without生产的”错误

Question

在一步一个脚印2.2（准备好您的Rails应用程序部署到Heroku的）RailsBridge的，系统会提示您在终端输入：

bundle install --without production 

不幸的是，正在打印出一条错误消息“系统找不到指定的路径”。然后继续告诉你，如果你给这个错误要求一个志愿者来帮助你编辑config/environments/production.rb。 StackOverflow，你是我的志愿者！请帮助，你是我唯一的希望。

这里是代码 “的Gemfile”：

source 'https://rubygems.org' 


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '4.2.5.2' 
# Use sqlite3 as the database for Active Record 
group :development, :test do

end

这里是代码 “production.rb”：

    # Settings specified here will take precedence over those in config/application.rb. 

    # Code is not reloaded between requests. 
    config.cache_classes = true

    config.eager_load = true

    config.assets.compile = false 

    # Asset digests allow you to set far-future HTTP expiration dates on all assets,

    # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies. 
    # config.force_ssl = true 

    # Use the lowest log level to ensure availability of diagnostic information

    config.log_level = :debug 

    # Prepend all log lines with the following tags.

    # Ignore bad email addresses and do not raise email delivery errors. 
    # Set this to true and configure the email server for immediate delivery to raise delivery errors. 
    # config.action_mailer.raise_delivery_errors = false 

    # Enable locale fallbacks for I18n (makes lookups for any locale fall back to 
    # the I18n.default_locale when a translation cannot be found). 
    config.i18n.fallbacks = true 

    # Send deprecation notices to registered listeners. 
    config.active_support.deprecation = :notify 

    # Use default logging formatter so that PID and timestamp are not suppressed. 
    config.log_formatter = ::Logger::Formatter.new 

    # Do not dump schema after migrations. 
    config.active_record.dump_schema_after_migration = false 
end 

在前进，这要归功于谁决定帮帮忙！
