Ruby on rails 获得；SQLite3:：CorruptException:数据库磁盘映像格式不正确；从rails控制台

我正在学习MichaelHartl的rails屏幕播放教程，在第7章中，为了测试用户显示页面，我试图向数据库添加一个用户。当我创建一个用户时，它会被回滚，并出现一个SQLite3:：CorruptException:数据库磁盘映像格式错误错误。对这个错误的研究建议停止“postfix”进程，但我没有安装postfix。有什么想法吗？请注意，我是新手，这很可能是我的一个简单错误！谢谢

听起来数据库已经损坏。您可以使用以下命令从头开始：

rake db:drop
rake db:create
rake db:migrate

---

对我来说，没有任何效果。我删除了所有*.sqlite3文件，然后运行

rake db:create
rake db:migrate

---

然后它成功了。

谢谢，成功了！不幸的是，我不能给你投票，因为我的声誉不高。如果你遵循rails教程，你可能还需要运行：rake db:populateBe carefull，此过程删除并新建数据库，其中的所有数据都将丢失。
