rake db：rails 4.0.0.rc1中的种子错误

Question

我有一个rails应用程序，它不会将数据加载到rake db:seed上的数据库。

我试图通过rake db:seed RAILS_ENV=developement --trace找出它后面的错误

  

**调用db：seed（first_time）

     

**执行db：seed

     

**调用db：abort_if_pending_migrations（first_time）

     

**调用环境（first_time）

     

**执行环境

     

rake aborted！

     

数据库配置未指定适配器
