無法通過「rack-recaptcha」啓動服務器gem

Question

我已按照rack-recaptcha readme中所述的步驟進行操作。

我已經完成了所有的步驟，而不是「你必須在你的gemfile中需要'rack-recaptcha'」。

服務器無法啓動，因爲有下列錯誤：

Uncaught exception: uninitialized constant Rack::Recaptcha 

我認爲，用「的Gemfile」的一步，我是跳過的，這是錯誤的原因。

但是，我不知道，我應該在哪裏尋找提到的「gemfile」？

幫助，請

更新：

的environment.rb是繼

# Be sure to restart your server when you modify this file 

# Specifies gem version of Rails to use when vendor/rails is not present 
RAILS_GEM_VERSION = '2.3.5' unless defined? RAILS_GEM_VERSION 

# Bootstrap the Rails environment, frameworks, and default configuration 
require File.join(File.dirname(__FILE__), 'boot') 

Rails::Initializer.run do |config| 
    # Settings in config/environments/* take precedence over those specified here. 
    # Application configuration should go into files in config/initializers 
    # -- all .rb files in that directory are automatically loaded. 

    # Add additional load paths for your own custom dirs 
    #config.load_paths += %W(#{RAILS_ROOT}/extras)

    # Activate observers that should always be running

    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}')] 
    config.i18n.default_locale = :ru 
end 

Answer 1

我已經想通了。

我必須補充「要求」語句的reCAPTCHA庫

Answer 2

的Gemfile是當你正在運行的Rails 2中的Rails 3引入了一個包裝元素你需要做一些稍微不同的事情。在你的environment.rb添加Rails::Initializer.run塊內這一行：

config.gem 'rack-recaptcha', :lib => 'rack/recaptcha'
