运行“rake db：migrate VERSION = 0”后重新迁移

Question

我创建了一个名为AddEntryTOMembers entry:decimal的迁移。然后我需要将小数更改为整数。当我运行rake db:rollback时，它已成功回滚，但当我重新运行rails g AddEntryTOMembers entry:integer时，它显示：

SQLite3::SQLException: duplicate column name: entry: ALTER TABLE "members" ADD "
entry" integerc:/Sites/roomapp/db/migrate/20150216143625_add_entry_to_members.rb
:3:in `change'
c:in `migrate'
Tasks: TOP => db:migrate
(See full trace by running task with --trace)

然后我在Stack Overflow上搜索并找到＆＃34; SQLite3::SQLException: duplicate column name while migrating＆＃34;。之后我跑了rake db:migrate VERSION=0 它回滚了所有的迁移。 但是当我再次运行rake db:migrate时，它显示我之前成功添加迁移的问题。

SQLite3::SQLException: duplicate column name: image: ALTER TABLE "members" ADD "
image" varcharc:/Sites/roomapp/db/migrate/20150206144138_add_image_to_members.rb
:3:in `change'
c:in `migrate'
Tasks: TOP => db:migrate
(See full trace by running task with --trace)

如何重新迁移所有迁移？
