使用RVM西纳特拉的应用程序加载错误的Active Record宝石 [英] Error loading Active Record gem with sinatra app using RVM

问题描述

我成立了一个项目级RVM宝石的西纳特拉的应用程序，我开始将连接到与活动记录的本地数据库。为了测试它，我试图运行下面的测试程序：

test.rb

 需要'rubygems的'＃可能不需要，这取决于平台
要求辛纳特拉
需要的ActiveRecord

类文章＆LT;的ActiveRecord :: Base的
结束

得到'/'做
  Test.establish_connection（
    ：适配器=＆GT; sqlite3的，
    ：数据库=＆GT; hw.db
  ）
  Test.first.content
结束
 

（摘自这个问题的答案：什么是同时使用西纳特拉跟一个数据库的最佳方式）

当我运行红宝石-rubygems test.rb 我得到这个错误：

<$p$p><$c$c>/Users/[user]/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `需要'：无法加载这样的文件 - ActiveRecord的（LoadError）

我已经安装了Active Record的宝石，并将其显示在创业板上市和 RVM电流显示正确的宝石。我是新来RVM，我认为这是值得做的是没有正确的负载路径，但我觉得我已经正确设置好一切，所以我倒是对什么是错AP preciate建议。谢谢你。

解决方案

据我可以告诉需要的ActiveRecord'已去precated。尝试使用

 要求'active_record
 

来代替。

I set up a project level RVM gemset for a sinatra app I am starting that will connect to a local database with Active Record. In order to test it I tried to run the below test app:

test.rb

require 'rubygems' # may not be needed, depending on platform
require 'sinatra'
require 'activerecord'

class Article < ActiveRecord::Base
end

get '/' do
  Test.establish_connection(
    :adapter => "sqlite3",
    :database => "hw.db"
  )
  Test.first.content
end

(Taken from the answer to this question: What's the best way to talk to a database while using Sinatra?)

When I run ruby -rubygems test.rb I get this error:

/Users/[user]/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- activerecord (LoadError)

I've already installed the Active Record gem and it shows up in gem list and rvm current displays the correct gemset. I am new to RVM and I think this is something to do with the it not having the correct load path but I feel like I've set everything up correctly so I'd appreciate suggestions on what's wrong. Thanks.

解决方案

As far as I can tell require 'activerecord' has been deprecated. Try using

require 'active_record'

instead.
