Ruby on rails -使用taps将数据库从SQLite迁移到PostgresQL

Question

我正在使用taps将数据库从sqlite3迁移到PostgresQL。我正在尝试启动sqlite数据库上的taps服务器，如下所示

$ taps server sqlite://db/development.sqlite3 user password

然而，我得到了以下消息，因此我认为它不能很好地工作。你能理解如下这类信息吗？

您必须强制使用更低版本的tilt，我会尝试tilt 0.8，因为那是sinatra 1.0发布时最新版本的tilt。请注意，taps是一个死项目，您可能应该考虑迁移到其他项目。您可以尝试：

sequel -C sqlite://db/development.sqlite3 postgres://user:password@host/database
