AMD64 上的 ruby​​ postgreSQL

Question

----------------编辑----------------

我已经尝试了@Duk 所说的，但仍然没有任何效果。多试了几次之后，我发现问题不在 DataMapper 上。事实上，在 AMD64 上失败的是 postgreSQL 适配器。

我有 PostgreSQL 的二进制发行版(在他们的网站上找到的最后一个)，我通过做一个

gem install...

有人可以帮助我吗？

---------------- 原创----------------

按照 DataMapper 网站的“入门”，我遇到了这个例子:

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

我安装了我的 postgre 数据库、DataMapper 和每个依赖项(包括开发工具包)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，出现了这个错误:

错误发生在“load_adapter”函数上:

    require "dm-#{name}-adapter"

显然找不到该文件。我已尝试按照建议手动包含适配器 here但没有成功。

有什么想法吗？谢谢

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