从 gem 中删除 heroku db:pull 后，我正在尝试使用水龙头。

 taps server mysql2://root@localhost/trappor2 taps taps123

C:/Ruby193/lib/ruby/gems/1.9.1/gems/sequel-3.20.0/lib/sequel/adapters/sqlite.rb:
62:in `initialize': SQLite3::CantOpenException: unable to open database file (Se

        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/sequel-3.20.0/lib/sequel/connec
tion_pool.rb:92:in `make_new'

是什么导致了这个错误？

我最近在水龙头上也遇到了一些困难。如果可以，请尝试切换到 PG 备份——这非常简单：
