Question

----------------编辑----------------

我已经尝试过@Duk所说的，但仍然没有任何效果。在尝试了一点之后，我发现问题不在DataMapper上。事实上，它是在AMD64上失败的postgreSQL适配器。

我有PostgreSQL的二进制发行版（在他们的网站上发现的最后一个）我通过做了所有的宝石

gem install...

有人可以帮助我吗？

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

在DataMapper网站的“入门”之后，我遇到了这个例子：

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

我安装了postgre数据库，DataMapper和每个依赖项（包括dev-kit）这是代码：

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')

但是当我运行它时，会发生以下错误：

“load_adapter”函数发生错误：

    require "dm-#{name}-adapter"

显然找不到该文件。我已尝试按照建议的here手动添加适配器，但没有成功。

有什么想法吗？感谢

你必须安装dm-postgres-adapter（gem install dm-postgres-adapter）然后安装data_mapper（gem install data_mapper）。

AMD64上的ruby postgreSQL
