紅寶石PostgreSQL的基於AMD64

Question

----------------編輯----------------

我試着杜克說了什麼，仍然沒有任何工作。 嘗試了一些之後，我發現問題不在DataMapper上。 事實上，它是在AMD64上失敗的postgreSQL適配器。

我的PostgreSQL的二進制分發版（最後一個在其網站上找到）和我做一個

gem install... 

有人能幫助我所有的寶石？

---------------- ORIGINAL ----------------

繼從 「入門」 DataMapper的網站，我跑過這個例子：

# A Postgres connection: 
DataMapper.setup(:default, 'postgres://localhost/the_database_name') 

我已經安裝postgre數據庫，DataMapper的每依賴性（包括開發-KIT） 下面的代碼：

gem 'data_mapper' 
require 'dm-core' 
require 'dm-migrations/adapters/dm-postgres-adapter' 
# If you want the logs displayed you have to do this before the call to setup 
DataMapper::Logger.new($stdout, :debug) 

# A Postgres connection: 
DataMapper.setup(:default, 'postgres://localhost/test') 

但磨片n個I運行它，出現此錯誤：

require "dm-#{name}-adapter" 

顯然，沒有找到文件：關於 「load_adapter」 功能發生

錯誤。 我試過按照建議here手動包含適配器，但沒有成功。

有什麼想法？謝謝

您必須安裝dm-postgres-adapter（gem install dm-postgres-adapter）然後安裝data_mapper（gem install data_mapper）。
