耙分貝：創建和軌道服務器

我是新來的回報率，並一直在努力完成入門鏈接耙分貝：創建和軌道服務器

http://guides.rubyonrails.org/getting_started.html

我得到兩個問題：

我不能跑rake db:create
我不能跑rake server

工作站是Unbuntu 12.04，Rails 3.2.8，Ruby 1.9.3p194。

[email protected]:~/NetBeansProjects/rails_work/blog/config$ rake db:create 
(in /home/mukeshk/NetBeansProjects/rails_work/blog) 
rake aborted! 
undefined method `active_record' for #<Rails::Application::Configuration:0x00000002080410> 

(See full trace by running task with --trace)

你的application.rb中是否包括活動記錄？ – 2012-08-15 07:45:10

添加到您的config/application.rb中：

require "active_record/railtie"

沒有幫助。同樣的錯誤 – 2012-08-15 13:35:18

聽起來像Rails的破碎配置。嘗試使用本教程，這是我學習Rails的地方，非常有幫助和詳細。 http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:up_and_running。另外檢查：http://stackoverflow.com/questions/6087919/rails-rake-dbcreate-error?rq=1和http://stackoverflow.com/questions/6122966/ruby-on-rails-error-rake-dbcreate ？rq = 1 – 2012-08-15 17:47:33

解決了> rails服務器的問題。我遵循http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec:up_and_running – 2012-08-16 18:50:20
