部署Rails应用程序期间heroku的工头启动错误

Question

我尝试着从Rails 3.2.6和Heroku开始。 我的Ruby版本是1.9.3，我的database.yml是这样的：

development:
  adapter: postgresql
  encoding: utf8
  reconnect: false
  database: iscubeonror_development
  pool: 5
  username: rails
  password: rails
  host: localhost

test:
  adapter: postgresql
  encoding: utf8
  reconnect: false
  database: iscubeonror_test
  pool: 5
  username: root
  password:
  host: localhost

production:
  adapter: postgresql
  encoding: utf8
  reconnect: false
  database: iscubeonror_production
  pool: 5
  username: root
  password:
  host: localhost

我的procfile是

web: bundle exec rails server thin -p $PORT -e $RACK_ENV

我在production.rb，development.rb和test.rb上有以下内容：

 config.active_support.deprecation = :notify
 config.active_support.deprecation = :stderr
 config.active_support.deprecation = :stderr

最后，我正在使用Windows，我的Gemfile是

gem 'rails', '3.2.6'
gem 'pg'
gem 'thin'
gem "foreman"

当在终端heroku日志上写它给我warnig为

2012-11-20T18:05:35+00:00 app[web.1]: => Call with -d to detach

当写在终端工头开始时，它给了我

D:\Kalpesh\web\iscubeonror> foreman start
19:37:27 web.1  | started with pid 3868
19:38:18 web.1  | You did not specify how you would like Rails to report depreca
tion notices for your $RACK_ENV environment, please set config.active_support.de
precation to :log, :notify or :stderr at config/environments/$RACK_ENV.rb

由于这个原因，我的瘦服务器没有启动，我该怎么办
虽然我按照https://devcenter.heroku.com/articles/rails3#deploy-your-application-to-heroku plz的所有步骤进行操作，请紧急回复我

Answer 1

您应该阅读：

You did not specify how you would like Rails to report depreca
tion notices for your $RACK_ENV environment, please set config.active_support.de
precation to :log, :notify or :stderr at config/environments/$RACK_ENV.rb

Answer 2

我认为您需要在.env中定义一些环境变量：

RACK_ENV=development
PORT=3000
