哈希的奇数列表（SyntaxError），尽管我使用的是 Ruby 1.8.7 哈希声明

Question

我正在尝试使用“activerecord”和 Ruby 1.8.7 连接到 Oracle 数据库，但在我的 Windows 7 机器上出现以下错误。我搜索了这个问题，发现 1.8 和 1.9 ruby​​ 声明 'Hash' 但是我使用的是 Ruby 1.8.7，我觉得我使用了正确的哈希声明，如果我错了，请纠正我。

这就是我的代码的样子

require 'rubygems'
gem "activerecord-oracle_enhanced-adapter"
require 'active_record'

ActiveRecord::Base.establish_connection(
    :adapter => "oracle_enhanced",
    :database => "someurl.net:1523/ABCAD",
    :username => "testing1",
    :password => "testing1")

class TestTable < ActiveRecord::Base
  set_table_name "TABLE_NAME"
  set_primary_key "ID"
end

TestTable.find(:all).each do |tt|
  p tt
end

nac = TestTable.new()

其他信息： 我的机器上有以下宝石： * 本地宝石 *

我使用以下 Rubygems 版本：

C:\Users\tester1>gem -v

1.4.2

我尝试使用 OCI8 进行连接，并且能够从 Oracle 数据库中获得响应，因此我的计算机没有连接问题。

irb(main):006:0> OCI8.new('testing1', 'testing1', 'someurl.net:1523/ABCAD').exec('select sysdate from dual') do |r| puts r.join(', ') end

错误消息显示您的错误来自 activerecord-oracle_enhancedadapter gem 内部，并且该 gem 具有 Ruby 1.9 样式的哈希。您可能会发现该 gem 的旧版本支持 Ruby 1.8 并切换到该版本。
