Ruby on rails 正在连接到由数据库\u URL指定的数据库,ruby-on-rails,heroku,heroku-postgres,Ruby On Rails,Heroku,Heroku Postgres,我一直在heroku日志中看到： 14-10-30T12:59:51+00:00 heroku[slug-compiler]: Slug compilation finished 2014-10-30T12:59:51.608050+00:00 heroku[web.1]: State changed from crashed to starting 2014-10-30T13:00:00.705131+00:00 heroku[web.1]: Starting process with com

在谷歌上查了几乎所有的答案

db：安装成功了

db：迁移成功了

config.assets.initialize\u on\u precompile=false已设置

不仅是heroku，我在本地生产环境中也遇到了同样的错误：

Macs-MacBook-Pro:v1 mac$ RAILS_ENV=production rails s
=> Booting WEBrick
=> Rails 3.2.13 application starting in production on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Connecting to database specified by database.yml
Exiting

这是database.yml

production:
  adapter: postgresql
  host: 127.0.0.1
  port: 5432
  encoding: unicode
  database: s1_development
  pool: 5
  username: postgres
  password: password

本地开发环境没有任何问题：(

我还能做什么？或者如何找到问题？

数据库URL是否设置为有效的数据库？例如，“psql”工作吗？是的，数据库已创建、迁移并且应该工作
