Question

在从gem中删除heroku db：pull之后，我正在尝试使用tap。

 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
quel::DatabaseConnectionError)
        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/sequel-3.20.0/lib/sequel/adapte

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

导致此错误的原因是什么？
