Heroku在db：migrate rake上引發錯誤

Question

當我試圖拋出heroku run rake db:migrate正如邁克爾·哈特爾（Michael Hartl）在RoR教程中所說的那樣，它拋出了以下內容：

Running rake db:migrate on shielded-reaches-4728... up, run.2183
rake aborted!
NoMethodError: undefined method 'configure' for #<SampleApp::Application:0x007efe8ced6138>

我能做什么？

更新：這是我的production.rb文件：

Rails.application.configure do

  config.cache_classes = true

  config.eager_load = true

  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  config.serve_static_assets = false

  config.assets.js_compressor = :uglifier

  config.assets.compile = false

  config.assets.digest = true

  config.log_level = :info

  config.i18n.fallbacks = true

  config.active_support.deprecation = :notify

  config.log_formatter = ::Logger::Formatter.new
  config.active_record.dump_schema_after_migration = false
end

看來您有這樣的事情

...

module SampleApp
  class Application < Rails::Application

...

在您的application.rb文件中。 在這種情況下，您需要在production.rb文件中進行更改

Rails.application.configure

至

SampleApp::Application.configure
