rake db:migrate rake 中止！标准错误：发生错误

Question

如果有人可以帮助至少了解问题的根源，我们将不胜感激。

我正在处理的项目迁移时遇到问题。我什至开始了一个全新的，但问题仍然是相同的。尝试执行 rake db:migrate 时出现错误消息 （已尝试使用默认数据库 sqlite3 和可选 postgresql 启动新项目），但是，在生成模型后（尝试使用 rails g scaffold 计划名称：名称 dep_date：datetime 和模型 - rails g 模型计划名称： name dep_date:datetime ) 迁移停止。

迁移本身是：

class CreateSchedules < ActiveRecord::Migration[5.0]
  def change
   create_table :schedules do |t|
     t.name :name
     t.datetime :dep_date
     t.timestamps
   end
 end
end

命令：rake db:migrate:status

给出以下内容：

database: travel_t_challenge_development

Status Migration ID Migration Name

down 20160809121048 Create schedules

命令：

rake db:migrate 

rake RAILS_ENV=production db:migrate or

rake db:migrate:up VERSION=20160809121048 or

bundle exec rake db:migrate VERSION=20160809121048

（或重做）

导致同样的错误：

再次删除和设置/创建数据库也无济于事。

试试这个，替换你的 CreateSchedules 迁移的更改方法。

def change
   create_table :schedules do |t|
     t.string :name
     t.datetime :dep_date
     t.timestamps null: false
   end
end
