在db:test:load with Rails上出现SQLException

我一直在开发一个小型但有些复杂的Rails应用程序，其中包含多个has_and_belongs_to_many关系。它是开源的，代码在这里。一切工作正常，但是最近我添加了一个新的HABTM关系迁移，一个rspec测试开始失败。Rake:db:migrate正常工作(并且问题在本地工作)，只是不在测试中。在运行db:test:load——trace时，我得到以下错误:

:fermi og$ rake db:test:load——trace/Users/og/.rvm/ruby/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).

我的模式。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.
ActiveRecord::Schema.define(:version => 20130519192155) do
  create_table "distributions", :force => true do |t|
    t.float    "mean"
    t.float    "spread"
    t.float    "wideness"
    t.datetime "created_at",   :null => false

任何帮助或信息将不胜感激。我在网上搜索这些错误已经有一段时间了，但在网上发现的很少。

对我有效的是删除schema。Rb，即模式定义文件。

(该文件的第一段注释建议删除它并生成一个新的，而不是编辑它。)

然后运行rake db:migrate，它执行所有迁移并重新创建模式。rb文件。

我也得到了类似的错误，我不知道。但是当我删除这些代码时，这里是

create_table "sqlite_sp_functions", :id => false, :force => true do |t|
  t.text "name"
  t.text "text"
end
# Could not dump table "sqlite_stat1" because of following StandardError
#   Unknown type '' for column 'tbl'
# Could not dump table "sqlite_stat3" because of following StandardError
#   Unknown type '' for column 'tbl'
create_table "sqlite_vs_links_names", :id => false, :force => true do |t|
  t.text "name"
  t.text "alias"
end
create_table "sqlite_vs_properties", :id => false, :force => true do |t|
  t.text "parentType"
  t.text "parentName"
  t.text "propertyName"
  t.text "propertyValue"
end
create_table "sqlite_vsp_diagrams", :id => false, :force => true do |t|
  t.text "name"
  t.text "diadata"
  t.text "comment"
  t.text "preview"
end

那么rake test:prepare可能行得通

在config/application.rb或config/environments/development.rb中添加以下配置行:

ActiveRecord::SchemaDumper.ignore_tables = /^sqlite_*/

这将在模式转储期间忽略数据库中所有以"sqlite_"开头的表。
