从rails控制台获取“SQLite3 :: CorruptException：数据库磁盘映像格式错误”
我正在做Michael Hartl的rails屏幕播放教程，在第7章中，我试图将用户添加到数据库中，以便测试用户显示页面。 当我创建一个用户时，它会被一个SQLite3 :: CorruptException回滚：数据库磁盘映像格式错误。 对此错误的研究建议停止“后缀”过程，但我没有安装postfix。 有任何想法吗？ 请注意，我是新手，这很可能是我的一个简单错误！ 谢谢！

rake db:drop rake db:create rake db:migrate
对我来说，没有什么工作。 我删除了所有* .sqlite3文件，然后运行
rake db:create rake db:migrate
然后它奏效了。
