ruby postgreSQL on AMD64

Question

“我试过了，”杜克说，但仍然没有效果。在尝试了更多之后，我发现问题不在DataMapper上。实际上，postgreSQL适配器在AMD64上失败了。

我有PostgreSQL的二进制发行版(最后一个在他们的站点上找到)，我通过做一个

gem install...

有人能帮我吗？

？

在DataMapper网站的“入门”之后，我看到了这个示例：

# 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)，下面是代码：

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，会发生这样的错误：

    from -e:1:in `<main>'

错误发生在"load_adapter“函数上：

    require "dm-#{name}-adapter"

很明显文件没找到。我尝试过像建议的here那样手动地包含适配器，但没有成功。

知道吗？谢谢

您必须安装data_mapper适配器(gem安装data_mapper适配器)，然后安装data_mapper(gem安装data_mapper)。
