ruby-on-rails-3 - 数据库 :test:load with Rails 上的 SQLException

Question

我一直在开发一个小型但有些复杂的 Rails 应用程序，它具有多个 has_and_belongs_to_many 关系。它是开源的，代码是here 。一切工作正常，但最近我添加了一个新的 HABTM 关系迁移，并且 rspec 测试开始失败。 Rake:db:migrate 正在工作(问题是在本地工作)，只是不在测试中。运行 db:test:load --trace 后，出现以下错误:

:fermi og$ rake db:test:load --trace /Users/og/.rvm/rubies/ruby-1.9.3-head/lib/ruby/1.9.1/yaml.rb:56:in <top (required)>': It seems your ruby installation is missing psych (for YAML output).

我的 schema.rb 文件如下:

# encoding: UTF-8
# This file is auto-generated from the current state of the database. Instead
# of editing this file, please use the migrations feature of Active Record to
# incrementally modify your database, and then regenerate this schema definition.
#
# Note that this schema.rb definition is the authoritative source for your
# database schema. If you need to create the application database on another
# system, you should be using db:schema:load, not running all the migrations
# from scratch. The latter is a flawed and unsustainable approach (the more migrations
# you'll amass, the slower it'll run and the greater likelihood for issues).
#
# It's strongly recommended to check this file into your version control system.

任何帮助或信息将不胜感激。我在网上搜索这些错误很长一段时间，但在网上发现的很少。

对我有用的是删除 schema.rb，它是架构定义文件。

(此文件中的第一段注释建议删除它并生成一个新的，而不是编辑它。)

然后只需运行 rake db:migrate，它会执行所有迁移并重新创建 schema.rb 文件。
