Heroku Rake和Heroku Push無效-Rails

Question

如果我嘗試運行：heroku rake db：migrate，這是我得到的錯誤：

rake aborted!
undefined local variable or method `config' for main:Object
/app/config/application.rb:4:in `<top (required)>'
/app/Rakefile:4:in `require'
/app/Rakefile:4:in `<top (required)>'

/app/vendor/bundle/ruby/2.0.0/bin/rake:23:in `load'
/app/vendor/bundle/ruby/2.0.0/bin/rake:23:in `<main>

運行：git push heroku master我得到這個：

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?

我嘗試向application.rb添加config.assets.initialize_on_precompile = false，但是它沒有幫助:(。

我嘗試推送的該應用曾經在heroku上，但是我不小心刪除了我的herokuapp。 請幫忙！

問題出在Rolify上，新版本出現了問題，所以我不得不退回到3.2.0。
