Question

我无法在我的rails项目上运行rake db:migrate。我收到这个错误：

/home/john/.rvm/gems/ruby-1.9.2-p290/gems/activerecord-3.0.5/lib/active_record/connection_adapters/sqlite3_adapter.rb:27: [BUG] unknown type 0x22 (0xc given)

[1]    2610 abort      rake db:migrate

（full traceback）

我尝试安装rake = 0.8.7，设置我的rails项目的Gemfile使用rake = 0.8.7，但我仍然得到相同的“uknown type”错误。

迁移文件：

class CreateProducts < ActiveRecord::Migration
  def self.up
    create_table :products do |t|
      t.string :title
      t.text :description
      t.string :image_url
      t.decimal :price, :precision => 8, :scale => 2

      t.timestamps
    end
  end

  def self.down
    drop_table :products
  end
end

Answer 1

根据this post by Mark Aufflick，可能是因为你安装了Ruby。

我建议卸载Ruby，然后使用RVM重新安装它。

Answer 2

你试过了吗？
