Heroku Rake和Heroku推不工作
如果我尝试运行：heroku rake db：migrate，这是我得到的错误：
rake aborted!
undefined local variable or method `config' for main:Object

运行：git push heroku master我得到这个：
Preparing app for Rails asset pipeline
Running: rake assets:precompile
rake aborted!
could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
我已经尝试添加：config.assets.initialize_on_precompile = false到application.rb但它没有帮助:(。
这个应用程序我试图推动曾经在heroku上，但我不小心删除了我的herokuapp。 请帮忙！
问题出在Rolify，新版本有问题，所以我不得不退到3.2.0。
